The Secretary of Health and Human Services (“government”) appeals the judgment of the United States Court of Federal Claims reversing the special master’s denial of Margaret Althen’s claim under the National Childhood Vaccine Injury Act of 1986, 42 U.S.C. § 300aa-1 to -34 (“Vaccine Act”), for loss of vision caused by a tetanus toxoid (“TT”) vaccination.
Althen v. Sec’y of Health & Human Servs.,
Background
On March 28, 1997, Margaret Althen, aged 49, received TT and hepatitis A vaccinations. Notwithstanding prior diagnoses of hypothyroidism and Duane’s Syndrome, 1 Althen enjoyed good health. On April 15, 1997, she sought medical treatment for an incessant headache, painful eye movements, and blurred vision in her right eye, which progressed in four days to a complete loss of sight in that eye. An ophthalmologist initially diagnosed Althen’s condition as right optic neuritis, inflammation of the optic nerve, which was confirmed by an April 21, 1997, magnetic resonance image. After subsequent complaints of vision impairment in her right eye and numbness in her right hand, she was diagnosed with significant right optic neuritis on May 23, 1997. On June 4, 1997, Althen was admit *1277 ted to the hospital after suffering from fever, confusion and neck stiffness. After several days of testing, she was discharged with a diagnosis of acute disseminated en-cephalomyelitis (“ADEM”), 2 right optic neuritis and congenital Duane’s syndrome.
Althen was again admitted to the hospital on July 2, 1997, because of dizziness and gait instability. On July 8, 1997, she was discharged after being diagnosed as possibly suffering from encephalitis 3 or ADEM. By June 4, 1998, her physician concluded that she had developed ADEM. On July 27, 1998, and January 7, 1999, Althen experienced optic neuritis in her left eye. On August 6, 2000, she suffered a brain seizure. A brain biopsy showed evidence of inflammation in the central nervous system, and she was diagnosed with vasculitis with secondary tissue destruction and demyelination consistent with primary angiitis. 4
Althen initiated her Vaccine Act claim on March 31, 2000. A special master of the Court of Federal Claims held an evi-dentiary hearing on June 14, 2002, and in a June 3, 2003, decision denied compensation upon determining that the TT vaccination did not cause Althen’s illness. Despite the testimony of Dr. Derek R. Smith, a board-certified neurologist with a subspecialty in neuroimmunology, that the TT shot caused her injury and that the onset of her optic neuritis occurred within a medically-accepted time period for causal connection, the special master found that because Al-then did not provide peer-reviewed literature that demonstrated “ ‘a suspected or potential association’ between
the tetanus toxoid vaccine
and the alleged injuries” as required by
Stevens v. Secretary of Health and Human Services,
No. 99-594V,
Althen sought review of the decision by the Court of Federal Claims, arguing that the special master erred as a matter of law by imposing the Stevens test to heighten her evidentiary burden. After concluding that the Stevens test was not in accordance with law and the special master’s reliance on it was in error, the court reversed, holding that Althen had proven causation in fact under the preponderant evidence standard set forth in the Vaccine Act. The court remanded to the special master for an award of compensation to Althen. The government appeals, and we have jurisdiction under 42 U.S.C. § 300aa-12(f).
Discussion
Under the Vaccine Act, the Court of Federal Claims reviews the special master’s decision to determine if it is “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law[.]” 42 U.S.C. § 300aa-12(e)(2)(B). Because
*1278
we review the trial court’s legal determination that the special master acted in a manner not in accordance with law
de novo,
we effectively review the special master’s decision under the same standard.
See Hines v. Sec’y of Health & Human Servs.,
The Act provides for the establishment of causation in one of two ways: through a statutorily-prescribed presumption of causation upon a showing that the injury falls under the Vaccine Injury Table (“Table injury”),
see
42 U.S.C. § 300aa-14(a); or where the complained-of injury is not listed in the Vaccine Injury Table (“off-Table injury”), by proving causation in fact,
see
42 U.S.C. §§ 300aa-13(a)(1), -11(c)(1)(C)(ii)(I). Althen sought redress for her illness under the Vaccine Act’s compensatory provision for off-Table injury. She must prove by a preponderance of the evidence that the TT vaccination caused her malady.
See Shyface v. Sec’y of Health & Human Servs.,
The government urges us to reinstate the special master’s initial ruling under the arbitrary or capricious standard of review. It posits that the trial court’s finding of causation, based upon its acceptance of Dr. Smith’s theory of causation over that of the government’s witnesses whose testimony the special master found more credible, was an improper reweighing of the evidence. While the government is correct that the trial court and this court review the special master’s factual findings under the arbitrary and capricious standard, the trial court based its reversal on a conclusion that the decision was not in accordance with law. See Althen II, 58 Fed.Cl. *1279 at 279. That was, of course, a legal conclusion based appropriately on de novo review. Thus, the true issues presented here are whether the special master’s finding that Althen had not established by a preponderance of the evidence a causal connection between her illness and her TT vaccination is in accordance with law; and if not, whether the Court of Federal Claims erred as a matter of law by finding causation under the proper standard.
I.
The disputed
Stevens
test requires that a claimant provide proof of: (1) medical plausibility; (2) confirmation of medical plausibility from the medical community and literature; (3) an injury recognized by the medical plausibility evidence and literature; (4) a medieally-aceeptable temporal relationship between the vaccination and the onset of the alleged injury; and (5) the elimination of other causes.
Stevens,
We see no “objective confirmation” requirement in the Vaccine Act’s preponderant evidence standard. The statute’s language is clear; section 300aa-13(a)(1) instructs that a petitioner must prove causation in fact by a “preponderance of the evidence,” substantiated by medical records
or
medical opinion, as to each factor contained in section 300aa-11(c)(1).
6
In turn, section 300aa-11 (c) (1) (C) (ii) (I) requires a claimant to provide evidence showing that she “sustained, or had significantly aggravated, any illness, disability, injury, or condition not set forth in the Vaccine Injury Table but which was caused by a vaccine referred to in subparagraph (A)[.]”
7
This court has interpreted the “preponderance of the evidence” standard referred to in the Vaccine Act as one of proof by a simple preponderance, of “more probable than not” causation.
See Hellebrand v. Sec’y of Health & Human Servs.,
The government’s postulate that the “heavy lifting” referred to in
Lampe v. Secretary of Health and Human Services,
Bring the case within the timetable and specifications of a Table Injury and the statute does the heavy lifting — causation is conclusively presumed. Failing that, the heavy lifting must be done by the petitioner, and it is heavy indeed. Given the statutory burden of persuasion placed upon the petitioner, 42 U.S.C. § 300aa-13(a)(1) ... it is not surprising that petitioners have a difficult time proving [off-Table cases].
The special master’s role is to apply the law. Questions of law regarding the interpretation or implementation of the Vaccine Act are matters for the courts.
See La Buy v. Howes Leather Co.,
We hold today that the special master’s application of the Stevens test was contrary to law. The special master’s role is to assist the courts by judging the merits of individual claims on a case-by-case basis, not to craft a new legal standard to be used in causation-in-fact cases. Moreover, given our holding that prong two of the Stevens test contravenes the plain language of the statute, prong three of the test (requiring an injury recognized by the medical plausibility evidence and literature) cannot fare any better. If the Vaccine Act does not require Althen to provide medical documentation of plausibility, then it cannot require her to demonstrate that her specific injury is recognized by said medical documentation of plausibility. The remainder of the Stevens test-requiring that the claimant provide proof of medical plausibility, a medically-acceptable temporal relationship between the vaccination and the onset of the alleged injury, and the elimination of other causes-is merely a recitation of this court’s well-established precedent.
II.
The next question is whether the trial court erred by finding that the TT vaccination caused Althen’s illness. The government argues that, even if we refuse to uphold the special master’s initial decision, the trial court nonetheless was wrong to make its own factual findings rather than remanding for a re-evaluation of the evidence under the proper legal test. We disagree.
As a preliminary matter, because the special master’s decision was not in accordance with law, the trial court was permitted to review the evidence anew and come to its own conclusion. 42 U.S.C. § 300aa-12(e)(2)(B);
8
Saunders v. Sec’y of Health & Human Servs.,
Althen established by a preponderance of the evidence that the TT vaccination caused her central nervous system demyelinating disorder. Her proffered evidence, which the trial court accepted as more convincing, provided the requisite showings of a medical theory causally connecting the vaccination and the injury, a logical sequence of cause and effect showing that the vaccination was the reason for the injury, and a proximate temporal relationship between the TT vaccination and her injury. There is no error in the court’s conclusion that the government failed to prove that factors unrelated to the vaccine were principally responsible for Althen’s ailment.
Conclusion
Accordingly, the judgment of the United States Court of Federal Claims is affirmed.
AFFIRMED.

. Duane’s Syndrome is a hereditary eye movement disorder which limits the ability to move the eye outward toward the ear (abduction) and, in most cases, the ability to move the eye inward toward the nose (adduction). Dorland’s Medical Dictionary 1816 (30th ed. 2003) (Dorland's). This ailment caused Al-then to experience double vision when looking to the left.
.ADEM is a demyelinating disease affecting the nerve fibers in the nervous system which "occurs most commonly following an acute viral infection ... but may occur without a recognizable antecedent.... It is believed to be a manifestation of an autoimmune attack on the myelin of the central nervous system. Clinical manifestations include fever, headache, vomiting, and drowsiness progressing to lethargy and coma; tremor, seizures, and paralysis may also occur[.]” Dorland's at 610.
. Encephalitis is inflammation of the brain. Dorland’s at 608.
. Vasculitis is an inflammation of the blood or lymph vessels. Dorland’s at 2009. Angiitis is isolated vasculitis of the central nervous system. Id. at 82. Althen’s illness is generally referred to as a central nervous system de-myelinating disorder.
. The government opposed the special master's use of the Stevens test, both in its brief and at oral argument where it asserted that application of the test is not always consistent with the statute because, in some cases, prong two sets the evidentiary barrier too low.
. Section 300aa-13(a)(1) states, in relevant part:
(a) General rule.
(1) Compensation shall be awarded under the Program to a petitioner if the special master or court finds on the record as a whole—
(A) that the petitioner has demonstrated by a preponderance of the evidence the matters required in the petition by section 2111(c)(1) [42 U.S.C. § 300aa-11(c)(1)], and
(B) that there is not a preponderance of the evidence that the illness, disability, injury, condition, or death described in the petition is due to factors unrelated to the administration of the vaccine described in the petition.
The special master or court may not make such a finding based on the claims of a petitioner alone, unsubstantiated by medical records or by medical opinion.
42 U.S.C. § 300aa-13(a)(1) (2000) (emphases added).
.Tetanus toxoid vaccine is referred to in the Vaccine Injury Table, subparagraph (A).
. Section 300aa-12(e)(2)(B) states, in relevant part:
(2) Upon the filing of a motion [to review the special master's decision], the [United States Court of Federal Claims] shall have jurisdiction to undertake a review of the record of the proceedings and may thereafter—
(B) set aside any findings of fact or conclusion of law of the special master found to be arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law and issue its own findings of fact and conclusions of law [.]
42 U.S.C. § 300aa-12(e)(2)(B) (emphasis added).
