Exploring the link between vitamin D and clinical outcomes in COVID-19
et al., American Journal of Physiology-Endocrinology and Metabolism, doi:10.1152/ajpendo.00517.2020
Retrospective 270 patients with vitamin D levels measured in the last year, showing no significant difference in outcomes based on vitamin D levels or vitamin D supplementation.

risk of death, 14.7% lower, RR 0.85, p = 0.56, high D levels 88, low D levels 95, odds ratio converted to relative risk, control prevalence approximated with overall prevalence, >30 ng/mL vs. <20 ng/mL, >30 ng/mL group size approximated.
