    ______________________
    Before DYK, SCHALL, and PROST, Circuit Judges.
    SCHALL, Circuit Judge
    DECISION
    The Secretary of Health and Human Services (the
    “government”) appeals the judgment of the United States
    Court of Federal Claims that reversed and remanded the
    Special Master’s denial of a claim for compensation filed
    by Mr. James L. Paterek (the “Petitioner”) under the
    Vaccine Act. See Doe 21 v. Sec’y of Health and Human
    Servs., 
    88 Fed. Cl. 178
    (2009) (the “Final Decision”).
    Because the Special Master properly denied the Petition-
    er’s claim, we reverse and remand with instructions to
    affirm the Special Master’s determination that the Peti-
    tioner is not entitled to compensation and to enter judg-
    ment for the government.
    DISCUSSION
    I. CASES UNDER THE VACCINE ACT
    Under the Vaccine Act, see 42 U.S.C. §§ 300aa-1 to
    300aa-34, a petitioner seeking compensation may prove
    causation in one of two ways, depending on whether the
    case involves “Table injuries” or “off-Table injuries.” See
    Moberly v. Sec’y of Health and Human Servs., 
    592 F.3d 1315
    , 1321 (Fed. Cir. 2010). First, if the administered
    vaccine and injury are listed in the Vaccine Injury Table,
    and the injury manifests itself within the specified time
    period, a petitioner receives a presumption of a causal
    link between the vaccination and the injury. See de
    Bazan v. Sec’y of Health and Human Servs., 
    539 F.3d 1347
    , 1351 (Fed. Cir. 2008); see also 42 U.S.C. § 300aa-
    11(c)(1)(C)(i) (not requiring a showing of causation for a
    Table injury); 42 U.S.C. § 300aa-14(a) (initial Vaccine
    Injury Table); 42 C.F.R. § 100.3 (current Vaccine Injury
    Table). Second, for injuries not listed in the Table, or
    JAMES PATEREK   v. HHS                                  3
    which do not occur within the specified time period, a
    petitioner seeking compensation must prove causation-in-
    fact. See de 
    Bazan, 539 F.3d at 1351
    ; see also 42 U.S.C.
    § 300aa-11(c)(1)(C)(ii) (requiring a showing of causation
    for an off-Table injury). This appeal involves only an
    alleged off-Table injury. To prove that a vaccination
    caused an off-Table injury, a petitioner must demonstrate,
    by a preponderance of the evidence, the following three
    prongs:
    (1) a medical theory causally connecting the vac-
    cination and the injury; (2) a logical sequence of
    cause and effect showing that the vaccination was
    the reason for the injury; and (3) a showing of a
    proximate temporal relationship between vaccina-
    tion and injury.
    Althen v. Sec’y of Health and Human Servs., 
    418 F.3d 1274
    , 1278 (Fed. Cir. 2005). If a petitioner establishes a
    prima facie case, the burden shifts to the government to
    establish an alternative causation by a preponderance of
    the evidence. See Walther v. Sec’y of Health and Human
    Servs., 
    485 F.3d 1146
    , 1151 (Fed. Cir. 2007); see also 42
    U.S.C. § 300aa-13(a)(1)(B) (noting that compensation will
    not be awarded if the injury “is due to factors unrelated to
    the administration of the vaccine”). If the government
    fails to do so, the petitioner is entitled to compensation.
    II. FACTS AND PRIOR DECISIONS
    The Petitioner seeks compensation for a diphtheria-
    tetanus-acellular pertussis (“DTaP”) vaccination that
    allegedly caused developmental delays in his son, J.P. On
    July 20, 1999, J.P. received the vaccination at his two-
    month well-baby examination. See Doe 21 v. Sec’y of
    Health and Human Serves., No. 02-0411V, 
    2009 WL 3288295
    , at *1 (Fed. Cl. Jan. 16, 2009) (“Special Master
    4                                    JAMES PATEREK   v. HHS
    Decision”). 1 At that examination, the treating pediatri-
    cian described J.P as “healthy” and noted, regarding gross
    motor development, that J.P. could “roll[] to side.” Later
    that evening, J.P. was admitted to the emergency room
    after having what the government has conceded was an
    adverse reaction—more specifically, a hypotonic-
    hyporesponsive episode (“HHE”)—to the DTaP vaccine.
    See 
    id. at *2. During
    this episode, J.P had crossed eyes
    and a fever, but was described as alert and in no acute
    distress. See 
    id. He was discharged
    approximately 75
    minutes later in satisfactory condition. See 
    id. At J.P.’s four-month
    well-baby examination on Sep-
    tember 14, 1999, the treating pediatrician described him
    as “well,” and noted that he could sit, hold up his head,
    and babble. See 
    id. The doctor discussed
    the risks and
    benefits of vaccinations with J.P.’s mother and, based on
    the previous HHE, gave J.P. only the diphtheria and
    tetanus vaccines rather than the DTaP vaccine, which
    also includes a component to prevent pertussis (commonly
    known as whooping cough). See 
    id. at *3. At
    a visit on October 4, 1999, J.P.’s primary treating
    pediatrician, Dr. Turow, noted the possibility of a “stra-
    bismus” or “pseudostrabismus” 2 based on reports from
    1    Under the Vaccine Act, a special master reviews
    each petition and issues a decision assessing whether
    compensation should be awarded. See 42 U.S.C. § 300aa-
    12(c), (d).
    2  Strabismus is commonly referred to as “lazy eye,”
    in which a person’s eyes are not properly aligned, usually
    because of a problem with the muscles around the eye.
    See Special Master Decision, 
    2009 WL 3288295
    , at *14.
    Pseudostrabismus is a similar lack of alignment brought
    about by causes other than a problem with the ocular
    muscles. See Final 
    Decision, 88 Fed. Cl. at 184
    n.17.
    JAMES PATEREK   v. HHS                                   5
    J.P.’s parents. As a result, he recommended an ophthal-
    mological consultation. See 
    id. Dr. Rubin, a
    pediatric
    ophthalmologist, examined J.P. on November 10, 1999,
    finding J.P. to be a “healthy 6 month old baby” with no
    evidence of strabismus. See 
    id. Dr. Rubin believed
    that
    any symptoms “would probably resolve spontaneously
    over the next several months.” See 
    id. At his sixth-month
    examination on November 8, 1999,
    J.P. was described as a “well infant,” who had good head
    control and could grab objects well. See 
    id. The doctor did
    note, however, that J.P. could not roll over and could
    not sit up without support. See 
    id. J.P. was referred
    to
    another doctor for a left eye “deviation medially.” 3 See 
    id. Like at the
    four-month examination, J.P. received the
    diphtheria and tetanus vaccines but not the pertussis
    component. See 
    id. On January 31,
    2000, at his nine-month well-baby ex-
    amination, J.P. was again described as “well,” with the
    doctor noting that he could sit indefinitely without sup-
    port, use a “pincer” grasp to pick up objects, speak basic
    syllables, wave, and play “peek-a-boo.” See 
    id. J.P. could not,
    however, pull himself up to stand or walk with the
    help of nearby support (known as “cruising”). See 
    id. On March 8,
    2000, Dr. Turow noted a potential con-
    cern about J.P.’s “developmental progression.” See 
    id. at *4. J.P.
    was diagnosed with “fine & gross motor develop-
    mental delay” on March 27, 2000. See 
    id. The examining specialist
    recommended physical therapy and monitoring.
    See 
    id. 3 A “deviation
    medially” is a strabismus in which an
    eye is pointed towards a person’s nose. See Special Mas-
    ter Decision, 
    2009 WL 3288295
    , at *15.
    6                                    JAMES PATEREK   v. HHS
    Two days later, an ophthalmologist observed and rec-
    orded a “vertical nystagmus.” 4 See 
    id. The next day,
    after
    J.P.’s mother told Dr. Turow that the vertical nystagmus
    appeared to be worsening, Dr. Turow referred J.P. to a
    pediatric neurologist. See 
    id. During his examination
    of
    J.P., the neurologist attempted to elicit, but did not ob-
    serve, any nystagmus. See 
    id. On April 5,
    2000, Dr.
    Rubin examined J.P. but also did not observe any nys-
    tagmus. See 
    id. The Petitioner filed
    a claim under the Vaccine Act on
    April 30, 2002, asserting that the DTaP vaccination
    administered on July 20, 1999, caused J.P.’s developmen-
    tal delays diagnosed in March of 2000. See 
    id. at *5. a.
    THE SPECIAL MASTER DECISION
    After a prior decision and remand not before us in this
    appeal, 5 the Special Master concluded that the Petitioner
    had failed to establish the second and third prongs re-
    quired under Althen, and was thus not entitled to com-
    pensation. See 
    id. at *22–30. The
    Special Master found
    that J.P was developing normally from July of 1999 to
    March of 2000, at which point, the government concedes,
    he was suffering from a brain disorder known as an
    encephalopathy, and was developmentally delayed. See
    
    id. at *5, *8.
    The Special Master rejected the opinion,
    held by experts for the Petitioner, that J.P. was signifi-
    4   A “vertical nystagmus” is a repetitive up-and-
    down fluttering of the eyes, usually associated with an
    underlying neurological problem. See Special Master
    Decision, 
    2009 WL 3288295
    , at *15.
    5   These two decisions relate to, but are not directly
    at issue in, this appeal. They are: Doe 21 v. Sec’y of
    Health and Human Servs., 02-0411V, 
    2008 WL 4679501
    (Fed. Cl. Oct. 14, 2008), and Doe 21 v. Sec’y of Health and
    Human Servs., 
    84 Fed. Cl. 19
    (2008).
    JAMES PATEREK   v. HHS                                  7
    cantly developmentally advanced at two months. See 
    id. at *9. While
    those experts assumed J.P. was rolling over
    (i.e., from front to back or vice versa), the Special Master
    pointed out that the pertinent notation actually reads
    that J.P. “rolls to side,” an activity perhaps only slightly
    advanced at two months. See 
    id. at *9–10. The
    Special
    Master also rejected the related view that J.P. was poten-
    tially experiencing developmental delays at four months
    because he was not “still” advanced at that time. See 
    id. at *10–12. As
    to J.P.’s condition at his six-month well-baby ex-
    amination, the Special Master found that a preponder-
    ance of the evidence established that J.P. was developing
    normally, and that the failure to roll over or sit up with-
    out support merely demonstrated uneven development
    rather than delay. See 
    id. at *12–13. The
    Special Master
    noted that Dr. Turow “could not express an opinion as to
    whether [J.P.] was developmentally delayed at six
    months” while Dr. Wiznitzer, the expert for the govern-
    ment, testified that he would have merely “monitored” a
    child in J.P.’s situation. See 
    id. at *13. Moreover,
    the
    Special Master was not persuaded by the Petitioner’s
    experts, Drs. Shane and Megson, who opined that J.P.
    was delayed at six months. See 
    id. According to the
    Special Master, their opinions were based on the assump-
    tion that a six-month-old should sit without support even
    though “a preponderance of the evidence indicates that
    most babies achieve this milestone at seven-months.” See
    
    id. Regarding the condition
    of J.P.’s eyes, the Special
    Master clarified the difference between strabismus and
    nystagmus, and stated that while “no credible evidence
    supports a finding that [J.P.] was suffering from a nys-
    tagmus in October and November 1999,” “a preponder-
    ance of the evidence supports a finding that [J.P.] suffered
    from intermittent strabismus.” See 
    id. at *16, *18.
    Thus,
    the Special Master found that any eye conditions were
    8                                     JAMES PATEREK   v. HHS
    muscular, rather than neurological, in origin. See 
    id. at *18. The
    Special Master also found that while “a prepon-
    derance of the evidence indicates that [J.P.] was still
    developing normally” at the time of his nine-month well-
    baby examination, “some evidence indicates that [J.P.]
    had not reached one milestone,” namely, J.P. could not
    cruise or pull himself to standing. See 
    id. at *18. Accord-
    ing to the Special Master, the experts supported the
    conclusion that J.P. was developing normally at this
    stage: Dr. Wiznitzer agreed that J.P. was developing
    normally but he would monitor him; Dr. Megson did not
    opine on delay, but instead noted the need for additional
    information about muscle tone prior to making an as-
    sessment; for his part, Dr. Shane did not give an opinion
    about J.P.’s development, believing the prior examination
    of J.P. was “limited.” See 
    id. For various reasons,
    the
    Special Master found Drs. Shane and Megson unpersua-
    sive and not credible as to certain critical points. See 
    id. at *19–21. Based
    on these findings, the Special Master concluded
    that the Petitioner had not satisfied the second prong
    under Althen because there “is little persuasive evidence
    to show that the July 20, 1999 DTaP vaccine caused
    [J.P.’s] failure to develop normally.” See 
    id. at *23. Specifically,
    the Special Master reasoned that, despite
    slightly missing two developmental milestones, J.P.’s
    otherwise normal development through the six-month
    well-baby examination “is not consistent with a child who
    had developed an encephalopathy on July 20, 1999.” See
    
    id. To demonstrate the
    lack of causation, the Special
    Master highlighted the testimony of Dr. Turow, who
    stated that “it was not impossible” that the DTaP vaccine
    caused the developmental delays, but would go no further.
    See 
    id. at *25. According
    to the Special Master, neither
    this testimony nor the other evidence set forth by the
    Petitioner satisfied the second prong. See 
    id. at *25–26. JAMES
    PATEREK   v. HHS                                  9
    The Special Master also concluded that the Petitioner
    had failed to establish prong three of Althen—a proximate
    temporal relationship between the vaccination and the
    injury. See 
    id. at *26. First,
    the Special Master found
    that the Petitioner had failed to present any evidence
    about the time frame that medical science would expect
    an injury caused by a vaccine to be manifest. See 
    id. at *26–27; see
    also de 
    Bazan, 539 F.3d at 1352
    (“Thus, the
    proximate temporal relationship prong requires prepon-
    derant proof that the onset of symptoms occurred within a
    timeframe for which, given the medical understanding of
    the disorder’s etiology, it is medically acceptable to infer
    causation-in-fact.”). Second, the Special Master found
    that the Petitioner had failed to establish that J.P.’s
    symptoms fell within the unidentified medically appropri-
    ate time period because, for the reasons noted above, J.P.
    was developing normally through March of 2000. See
    Special Master Decision, 
    2009 WL 3288295
    , at *27–30.
    The Special Master made no finding as to Althen prong
    one. See 
    id. at *22. b.
    THE FINAL DECISION
    On review of the Special Master Decision, the Court of
    Federal Claims determined that the Petitioner had estab-
    lished all three prongs under Althen, and thus remanded
    for an award of compensation. See Final Decision, 88 Fed.
    Cl. at 198–202. As to the first prong, the court held that
    the Petitioner had established a “medical theory causally
    connecting the vaccination and theory” because the Vac-
    cine Injury Table indicates that DTaP vaccines can cause
    encephalopathy—a causal connection “well recognized by
    the Office of Special Masters.” See 
    id. at 199. Regarding
    the second prong, the Court of Federal
    Claims found sufficient evidence of a logical sequence of
    cause and effect for three reasons. First, the court found
    support in Dr. Turow’s testimony because causation can
    be found “even where the treating physician cannot
    10                                    JAMES PATEREK   v. HHS
    unequivocally state that the vaccination caused the
    injury.” See 
    id. at 200 (citing
    Andreu v. Sec’y of Health
    and Human Servs., 
    569 F.3d 1367
    , 1375–76 (Fed. Cir.
    2009)). The court found that “[a]lthough Dr. Turow did
    not testify that the July 20, 1999 vaccine definitely caused
    Petitioner’s condition, he ‘believed’ that was the case
    here.” See Final 
    Decision, 88 Fed. Cl. at 200
    . Second, the
    court noted that “there was no other evidence that ex-
    plained [J.P.’s] injury.” See 
    id. Third, the court
    was
    persuaded by the fact that, after administering the per-
    tussis component in the first vaccination, J.P.’s treating
    physicians did not administer that component in later
    vaccinations, instead only administering the diphtheria
    and tetanus components. See 
    id. at 201. The
    court found the proximate temporal relationship
    required under the third prong of Althen satisfied because
    the government conceded that J.P. had suffered an HHE
    after receiving the DTaP vaccine. See 
    id. at 199. The
    court also found that J.P.’s medical records showed signs
    of developmental delay as early as November 1999. See
    
    id. at 202. First,
    the court determined that, based upon
    its review of the medical records, “by October 4, 1999,
    nystagmus may have been present, but escaped Dr.
    Rubin’s attention or simply was misdiagnosed.” See 
    id. Second, the court
    found that J.P.’s failure to roll over or
    sit up without support was not a sign of uneven develop-
    ment, as the Special Master had found, but rather a
    “digression” that represented “a missed developmental
    milestone.” See 
    id. Having found causation,
    the court
    reversed and remanded to the Special Master for an
    award of compensation. See 
    id. at 202. The
    Special
    Master awarded $2,431,153.51 for life care expenses for
    the first two years after judgment, $75,000 in compensa-
    tion for past unreimbursable expenses, and an amount
    sufficient to purchase an annuity contract.
    JAMES PATEREK   v. HHS                                 11
    The government timely appealed the judgment of the
    Court of Federal Claims awarding compensation. This
    court has jurisdiction pursuant to 42 U.S.C. § 300aa-12(f).
    III. STANDARD OF REVIEW
    In Vaccine Act cases, we review de novo a decision by
    the Court of Federal Claims, applying the same standard
    of review as that court applies in reviewing a decision of a
    special master. See Porter v. Sec’y of Health and Human
    Servs., 
    663 F.3d 1242
    , 1248–49 (Fed. Cir. 2011); Ha-
    zelhurst v. Sec’y of Health and Human Servs., 
    604 F.3d 1343
    , 1348–49 (Fed. Cir. 2010). Under that standard, we
    uphold factual findings that are not arbitrary and capri-
    cious and review legal conclusions to assess whether they
    accord with the law. 6 See 
    Moberly, 592 F.3d at 1321
    ; see
    also Munn v. Sec’y of Health and Human Servs., 
    970 F.2d 863
    , 870 n.10 (Fed. Cir. 1992) (clarifying the standard set
    forth in 42 U.S.C. § 300aa-12(e)(2)(B)).
    The arbitrary and capricious standard provides a fact
    finder the most deference possible. See 
    Munn, 970 F.2d at 870
    . Under that standard, “[i]f the special master has
    considered the relevant evidence of record, drawn plausi-
    ble inferences, and articulated a rational basis for the
    decision, ‘reversible error will be extremely difficult to
    demonstrate.’” See Hazelhurst, 
    604 F.3d 1343
    at 1349
    (quoting Hines v. Sec’y of Health and Human Servs., 
    940 F.2d 1518
    , 1528 (Fed. Cir. 1991)). In other words, as long
    as a special master’s factual finding is based on record
    6    The Petitioner relies on Hines v. Secretary of
    Health and Human Services, 
    940 F.2d 1518
    , 1523 (Fed.
    Cir. 1991), for the proposition that this court reviews
    factual findings for “clear error.” See Appellee Br. 30.
    The cited discussion from Hines makes clear, however,
    that, after statutory amendments made in 1989, that less

    by a special master.

    evidence that is “not wholly implausible, we are compelled
    to uphold that finding as not being arbitrary or capri-
    cious.” See Lampe v. Sec’y of Health and Human Servs.,
    
    219 F.3d 1357
    , 1363 (Fed. Cir. 2000). A court reviewing a
    special master’s decision should not “reweigh the factual
    evidence, assess whether the special master correctly
    evaluated the evidence, or examine the probative value of
    the evidence or the credibility of the witnesses—these are
    all matters within the purview of the fact finder.” See
    
    Porter, 663 F.3d at 1249
    .
    IV. ANALYSIS
    On appeal, the government argues that the Court of
    Federal Claims legally erred by substituting its own
    factual findings for those already made by the Special
    Master. According to the government, the court should
    have deferred to the Special Master’s findings, which were
    never explicitly found to be arbitrary or capricious. The
    Petitioner responds that the first symptoms of delay
    should be deemed the onset of a vaccine-related injury,
    even if the first symptoms predate the diagnosis of the
    injury. Here, according to the Petitioner, the eye move-
    ments reported by J.P.’s parents in October of 1999, as
    well as the potential indications of motor skill delays in
    November of 1999, represent early evidence supporting a
    finding that J.P. was, in fact, suffering from an encepha-
    lopathy soon after the first vaccination.
    Based on the record, we agree with the government
    and conclude that the Court of Federal Claims erred in
    rejecting the Special Master’s determination that the
    Petitioner failed to demonstrate entitlement to compensa-
    tion. To resolve this appeal, we only need address the
    second prong under Althen—a logical sequence of cause
    and effect showing that the vaccination was the reason for
    J.P.’s developmental delays. We will first explain why the
    findings in the Special Master Decision regarding prong
    two were not arbitrary or capricious and why his legal
    JAMES PATEREK   v. HHS                                 13
    conclusions accorded with the law. Then we will turn to
    the analysis of the Court of Federal Claims in the Final
    Decision.
    a. THE SPECIAL MASTER DECISION
    As noted, the Special Master’s determined that the
    Petitioner failed to establish the second prong under
    Althen—a logical sequence of cause and effect. See Spe-
    cial Master Decision, 
    2009 WL 3288295
    , at *22–26. The
    government has conceded two of the three necessary links
    in the causal chain: (1) that the DTaP vaccine caused the
    HHE on July 20, 1999, see 
    id. at *2; and
    (2) that whatever
    caused the encephalopathy (which the government admits
    was present by March of 2000) also caused the develop-
    mental delays, i.e., the relevant injury to J.P., see 
    id. at *5. The
    issue here is whether the vaccination (or HHE)
    caused the encephalopathy and developmental delays.
    For the following reasons, we conclude that the Special
    Master’s determination that the Petitioner failed to show
    this linkage by a preponderance of the evidence was not
    arbitrary or capricious, or tainted by legal error.
    In his decision, the Special Master conducted a
    thorough review of the relevant evidence, including the
    testimony of the expert witnesses, and concluded that the
    medical records did not support a finding that J.P. devel-
    oped an encephalopathy at the time of the HHE. See 
    id. at *23. In
    reaching that conclusion, the Special Master
    provided a reasoned explanation for crediting the gov-
    ernment’s expert, Dr. Wiznitzer, who testified that the
    failure to roll over and sit up without support at the six-
    month examination were not signs of an encephalopathy
    beginning in July of 1999. See 
    id. at *12–13. The
    Special
    Master found additional support for his conclusion in a
    note from a pediatric neurologist, Dr. Eviatar, who wrote
    that “[i]t is my medical opinion that [J.P.’s] developmental
    delay and immature eye movements are the result of
    congenital hydrocephalus and Arnold Chiara malfor-
    14                                    JAMES PATEREK   v. HHS
    mation . . . and are not related to [diphtheria-pertussis-
    tetanus] encephalopathy.” See 
    id. at *24. Further,
    the
    Special Master highlighted the testimony of Dr. Turow,
    who “was quite clear that he could not say that the DTaP
    [vaccine] caused the developmental delay.” See 
    id. at *25 (citing
    testimony at J.A. 388–90). Under the highly
    deferential standard applicable here, the Special Master’s
    reasoned conclusions regarding prong two of Althen were
    not arbitrary or capricious, and should be upheld. See
    
    Hazelhurst, 604 F.3d at 1349
    ; 
    Lampe, 219 F.3d at 1363
    .
    b. THE FINAL DECISION
    We turn now to the analysis in the Final Decision
    regarding the second prong of Althen. See Final 
    Decision, 88 Fed. Cl. at 199–201
    . In that regard, we conclude that
    the Court of Federal Claims generally failed to apply the
    highly deferential standard applicable to its review of the
    Special Master Decision; rather than assessing whether
    the Special Master’s findings were arbitrary and capri-
    cious, the court instead reevaluated the evidence and
    came to its own findings. This constitutes legal error. See
    
    Munn, 970 F.2d at 870
    (“The Claims Court owes these
    findings and conclusions by the special master great
    deference—no change may be made absent first a deter-
    mination that the special master was arbitrary and
    capricious.”); see also 
    Porter, 663 F.3d at 1249
    (cautioning
    a reviewing courts not to “reweigh the factual evidence,
    assess whether the special master correctly evaluated the
    evidence, or examine the probative value of the evidence
    or the credibility of the witnesses”); 
    Hazelhurst, 604 F.3d at 1349
    (noting that a reviewing court may not “second-
    guess the special master’s fact-intensive conclusions,
    particularly where the medical evidence of causation is in
    dispute”).
    One example of the court’s reweighing of the evidence
    here is its reliance on the testimony of Dr. Turow as one
    of the three bases supporting a finding of a logical se-
    JAMES PATEREK   v. HHS                                 15
    quence of cause and effect between the vaccination and
    the injury. When discussing the potential causation
    between the vaccination and the developmental delays in
    J.P., Dr. Turow stated that it was “not impossible,” but
    that he did not “have concrete evidence to connect the
    two.” See Final 
    Decision, 88 Fed. Cl. at 200
    (excerpting
    the relevant testimony). The Special Master relied on
    this same testimony to support a finding that the Peti-
    tioner did not establish causation. See Special Master
    Decision, 
    2009 WL 3288295
    , at *25 (“Like Dr. Turow’s
    written statements, his testimony falls short of the stand-
    ard of evidence that supports a finding of ‘a logical se-
    quence of cause and effect.’”). The Court of Federal
    Claims, however, reinterpreted Dr. Turow’s testimony to
    support causation, finding that he, in fact, “believed” that
    the vaccination caused J.P.’s condition. 7 See Final Deci-
    
    sion, 88 Fed. Cl. at 200
    . In so doing, the court erred first
    by failing to explain why the Special Master’s contrary
    finding was arbitrary or capricious, see 
    Munn, 970 F.2d at 870
    , and second by improperly reweighing the Turow
    testimony, see 
    Porter, 663 F.3d at 1249
    .
    In its analysis, the court also erred, we think, in its
    application of this court’s decisions in Andreu v. Secretary
    of Health and Human Services, 
    569 F.3d 1367
    (Fed. Cir.
    2009), and Capizzano v. Secretary of Health and Human
    Services, 
    440 F.3d 1317
    (Fed. Cir. 2006), to support its
    finding regarding the second prong. See Final 
    Decision, 88 Fed. Cl. at 199–201
    . The court relied on Andreu for
    the proposition that “the testimony of a treating physician
    7     At oral argument, counsel for the Petitioner con-
    ceded that this finding by the Court of Federal Claims
    was “a clear mistake.” See Oral Argument at 13:10–
    13:50, Paterek v. Sec’y of Health and Human Servs., No.
    2012-5078 (Fed. Cir. Apr. 5, 2013), available at
    http://oralarguments.cafc.uscourts.gov/default.aspx?fl=20
    12-5078.mp3.
    16                                    JAMES PATEREK   v. HHS
    can establish a logical sequence of cause and effect, even
    where the treating physician cannot unequivocally state
    that the vaccination caused the injury.” See 
    id. at 200 (citing
    Andreu, 569 F.3d at 1376
    ). This overstates the
    weight of equivocal testimony, such as Dr. Turow’s. In
    Andreu, one physician had already testified unequivocally
    as to causation, leaving the equivocal testimony from
    another physician to merely provide some additional
    support. See 
    Andreu, 569 F.3d at 1375–76
    . Thus, Andreu
    does not stand for the proposition that equivocal testimo-
    ny alone can establish causation. More importantly, as
    reasonably concluded by the Special Master, see Special
    Master Decision, 
    2009 WL 3288295
    , at *25, Dr. Turow’s
    testimony that causation was “not impossible” fails to
    provide support for causation at all. As this court has
    previously held, the statutory standard requires more
    than just “proof of a ‘plausible’ or ‘possible’ causal link
    between the vaccine and the injury.” See 
    Moberly, 592 F.3d at 1322
    .
    We also find error in the court’s application of Andreu
    and Capizzano to the two other bases relied on by the
    court to support the finding that the Petitioner estab-
    lished the second prong: that “there was no other evidence
    that explained [J.P.’s] injury” and that J.P.’s treating
    physicians withheld future administration of the pertus-
    sis vaccine. See Final 
    Decision, 88 Fed. Cl. at 200
    –01
    (citing 
    Andreu, 569 F.3d at 1375–77
    and 
    Capizzano, 440 F.3d at 1326
    ). In both Andreu and Capizzano, unlike
    here, the treating physician affirmatively concluded that
    the vaccine did, in fact, cause the injury. See 
    Andreu, 569 F.3d at 1376
    (noting that the relevant expert “stated
    unequivocally” that he believed that the vaccine caused
    seizures); 
    Capizzano, 440 F.3d at 1326
    (holding that “the
    chief special master erred in not considering the opinions
    of the treating physicians who concluded that the vaccine
    was the cause of Ms. Capizzano’s injury”). In the absence
    of an affirmative conclusion as to causation, the lack of an
    JAMES PATEREK   v. HHS                                 17
    alternative cause does not, alone, satisfy a petitioner’s
    burden. See 
    Althen, 418 F.3d at 1278
    (stating that “nei-
    ther a mere showing of a proximate temporal relationship
    between vaccine and injury, nor a simplistic elimination
    of other potential causes of the injury suffices, without
    more, to meet the burden of showing actual causation”);
    
    Hodges, 9 F.3d at 960
    . 8 Similarly, given Dr. Turow’s
    testimony, the decision to withhold future administration
    of the pertussis vaccine provides little probative evidence
    of causation. See 
    Andreu, 569 F.3d at 1376
    –77. For these
    reasons, we conclude that the Court of Federal Claims
    erred in finding the second prong under Althen satisfied.
    Lastly, we briefly address the conclusion that the
    Special Master committed legal error by allegedly engag-
    ing in a “[s]elective review” of J.P.’s medical records. See
    Final 
    Decision, 88 Fed. Cl. at 201
    . We can discern no
    basis for this conclusion. Although the Special Master did
    state that “[t]he details of most events in [J.P.’s] medical
    history after April 2000 are generally not relevant to
    determining whether the July 20, 1999 DTaP vaccination
    caused [J.P.’s] developmental delay,” he also made clear
    that “[a]lthough details of [J.P.’s] medical history after
    April 2000 are not set forth in this decision, these details
    appear in the two previous opinions and have been consid-
    ered.” See Special Master Decision, 
    2009 WL 3288295
    , at
    *5 (emphasis added). Finding certain information not
    relevant does not lead to—and likely undermines—the
    conclusion that it was not considered. This alleged error
    of law was not a proper basis to reverse the Special Mas-
    ter.
    8    We note that while causation cannot generally be
    based on the mere lack of an alternative cause alone, a
    petitioner may affirmatively rule out other possible alter-
    native causes to prove causation-in-fact. See de 
    Bazan, 539 F.3d at 1352
    n.3.
    18                                  JAMES PATEREK   v. HHS
    For these reasons, we reverse the judgment of the
    Court of Federal Claims and remand with the instruction
    that the court affirm the Special Master’s determination
    that the Petitioner is not entitled to compensation.
