Prospective study of 250 healthcare workers in the USA. The results are unclear - Figure 3 shows ~40% lower incidence with vitamin D supplementation, while the text indicates OR 1.18.
Authors collected symptom information, stating that "55% were symptomatic; the most common symptoms were cough, sore throat, and loss of taste or smell. Nine participants (16%) sought medical care...", but provide no information on symptoms per group for vitamin D supplementation. It is unclear what the definition of infection is - based on the antibody tests only, or also including self-reported cases? The meaning of increased antibodies is also not clear - vitamin D may improve antibody production.
Authors state "Despite a lack of evidence, a recent study found that nearly 70% of health care workers reported recommending vitamin D supplements...", however there is extensive evidence. There are currently 107 studies showing 37% [31‑42%] lower risk, including 26 RCTs showing 31% [17‑42%] lower risk.
Authors perform multivariable analysis for serum levels, but do not provide the results other than indicating they did not reach statistical significance. Similarly, they note no significant association between levels and symptoms, without providing any details. Authors do not provide multivariable analysis for supplement use. Authors make no comment on symptom prevalence for supplement use. Discussion is biased, for example referencing only 4 of the 25 RCTs at the time, strongly biased towards those reporting lower efficacy. No baseline information per group is provided.
38% of patients were lost to followup. We could not find any prospective registration or protocol. Funding was disclosed from Novartis and Radius Pharmaceuticals (whose lead product abaloparatide is an osteoporosis treatment).
