Retrospective study finding that regular bolus vitamin D supplementation was associated with less severe COVID-19 and better survival in frail elderly.
For those receiving regular supplementation:
Adjusted mortality hazard ratio with supplementation HR 0.07, p = 0.017.
Risk of severe COVID-19 with supplementation OR 0.08, p = 0.033.
For supplementation started after COVID-19 diagnosis:
Adjusted mortality hazard ratio HR 0.37, p = 0.28.
Risk of severe COVID-19 with supplementation OR 0.46, p = 0.4.
