Retrospective 144 patients in the USA showing significantly lower mortality for vitamin D levels >=30ng/mL.
This is the 38th of 184 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 712 vigintillion).
risk of death, 88.0% lower, RR 0.12, p = 0.01, high D levels 6 of 65 (9.2%), low D levels 20 of 79 (25.3%), NNT 6.2, adjusted per study, >30ng/mL, supplementary table 2, multivariable logistic regression model 5.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
