Vitamin D3 supplementation during or just before COVID-19 was associated with 68% lower mortality and less severe COVID-19 in frail elderly.
Retrospective 66 French nursing home residents, mean age 87.7, 9 control patients, and 57 that received an oral bolus of 80,000 IU vitamin D3 either in the week following the suspicion or diagnosis of COVID-19, or during the previous month. 17.5% mortality in the treatment group and 55.6% in the control group.
risk of death, 89.0% lower, RR 0.11, p = 0.002, treatment 10 of 57 (17.5%), control 5 of 9 (55.6%), NNT 2.6, adjusted per study.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
