Key PointsQuestionWhat is the effect of a single high dose of vitamin D3 on hospital length of stay among hospitalized patients with moderate to severe coronavirus disease 2019 (COVID-19)? FindingsIn this randomized clinical trial that involved 240 hospitalized patients with moderate to severe COVID-19, a single dose of 200 000 IU of vitamin D3, compared with placebo, did not significantly reduce hospital length of stay (median of 7.0 vs 7.0 days; unadjusted hazard ratio for hospital discharge, 1.07). MeaningThe study does not support the use of a high dose of vitamin D3 for treatment of moderate to severe COVID-19 in hospitalized patients.
