Retrospective 439 diabetic hospitalized patients in Saudi Arabia showing lower mortality with vitamin D >12.5 nmol/L, adjusted hazard ratio aHR 0.14, p = 0.007.
This is the 31st of 175 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 18 vigintillion).
risk of death, 85.7% lower, RR 0.14, p = 0.007, high D levels 111, low D levels 328, inverted to make RR<1 favor high D levels, >12.5 nmol/L.
