Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020, now with p < 0.00000000001 from 122 studies, recognized in 9 countries.
No treatment is 100% effective. Protocols combine treatments.

Retrospective 80 hospitalized patients in Spain showing higher risk of severe COVID-19 with vitamin D deficiency.
This is the 21st of 211 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 248,027,826 vigintillion).
risk of severe case, 55.0% lower, RR 0.45, p = 0.07, high D levels 11 of 35 (31.4%), low D levels 20 of 45 (44.4%), NNT 7.7, inverted to make RR<1 favor high D levels, odds ratio converted to relative risk, >20ng/mL.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
