Retrospective 88 COVID-19 hospitalized patients and 122 controls, showing higher mortality, ventilation, and length of stay with vitamin D deficiency.
risk of death, 81.1% lower, OR 0.19, p = 0.008, cutoff 20ng/mL, adjusted per study, 25-OH-D3, multivariable, RR approximated with OR.
risk of mechanical ventilation, 52.8% lower, OR 0.47, p = 0.13, cutoff 20ng/mL, adjusted per study, 25-OH-D3, multivariable, RR approximated with OR.
risk of no hospital discharge, 74.0% lower, HR 0.26, p < 0.001, cutoff 20ng/mL, 25-OH-D3, Cox proportional hazards.
