Effect of Daily Vitamin E and Multivitamin-Mineral Supplementation on Acute Respiratory Tract Infections in Elderly Persons: A Randomized Controlled Trial
Open accessAbstract
Context Immune response in elderly individuals has been reported to improve after micronutrient supplementation. However, efficacy trials evaluating infectious diseases as outcomes are scarce and inconclusive. Objective To investigate the effect of daily multivitamin-mineral and vitamin E supplementation on incidence and severity of acute respiratory tract infections in elderly individuals. Design A randomized, double blind, placebo-controlled, 2 x 2 factorial trial. Setting and participants A total of 652 noninstitutionalized individuals aged 60 years or older enrolled from 2 community-based sampling strategies in the Wageningen area of the Netherlands, conducted from 1998 to 2000. At baseline, 6% of participants had suboptimal ascorbic acid and 1.3% had suboptimal alpha-tocopherol plasma concentration. Intervention Physiological doses of multivitamin-minerals, 200 mg of vitamin E, both, or placebo. Main outcome measures Incidence and severity of self-reported acute respiratory tract infections at 15 months, as assessed by a nurse (telephone contact), home visits, and microbiological and serological testing in subsets of patients. Results During a median observation period of 441 days, 443 (68%) of 652 participants recorded 1024 respiratory tract infection episodes. The incidence rate ratio of acute respiratory tract infection for multivitamin-mineral supplementation was 0.95 (95% confidence interval, 0.75-1.15; P =.58) and for vitamin E supplementation, 1.12 (95% confidence…

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.
