Vitamin C prophylaxis in marine recruits
Abstract
A prospective, randomized, double-blind study was carried out to determine whether vitamin C prophylaxis, 2.0 g/day, vs placebo prophylaxis would reduce the incidence or morbidity of the common cold and other respiratory illnesses in 674 marine recruits during an eight-week period. Whole-blood ascorbic acid levels measured six weeks after initiation of the study were significantly higher in the vitamin C group. There was no difference between the two groups in the incidence or duration of colds. The vitamin C group rated their colds as being less severe, but this was not reflected in different symptom complexes or in fewer sick-call visits or training days lost. This study and the literature do not support the prophylactic use of vitamin C to prevent the common cold.

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.
