TriNetX PSM retrospective 42,674 COVID-19 outpatients, showing higher mortality and hospitalization with vitamin D deficiency.
This is the 190th of 199 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 835,162 vigintillion).
risk of death, 42.8% lower, HR 0.57, p = 0.005, high D levels (≥20 ng/mL) 8,300, low D levels (<20 ng/mL) 8,300, inverted to make HR<1 favor high D levels (≥20 ng/mL), propensity score matching.
