Abstract

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system of unknown etiology. We tested the hypothesis that MS is caused by Epstein-Barr virus (EBV) in a cohort comprising more than 10 million young adults on active duty in the US military, 955 of whom were diagnosed with MS during their period of service. Risk of MS increased 32-fold after infection with EBV but was not increased after infection with other viruses, including the similarly transmitted cytomegalovirus. Serum levels of neurofilament light chain, a biomarker of neuroaxonal degeneration, increased only after EBV seroconversion. These findings cannot be explained by any known risk factor for MS and suggest EBV as the leading cause of MS.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • EBV infection is a necessary risk factor for MS, and cross-reactive immune responses between EBV antigens and CNS proteins may contribute to disease initiation.

    “This phenomenon is particularly relevant considering recent data demonstrating that EBV infection is a necessary risk factor for MS and that cross-reactive immune responses between EBV antigens and CNS proteins may contribute to disease initiation [211, 212].”
  • Increasing evidence supports viral infections as triggers of autoimmune diseases in general; type 1 diabetes mellitus has been linked to enterovirus infections and multiple sclerosis to Epstein-Barr virus infections.

    “For example, type 1 diabetes mellitus was linked to enterovirus infections185 and multiple sclerosis to Epstein–Barr virus (EBV) infections186.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
