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.
5,100+ studies for 109 treatments. c19early.org
Systematic review and meta analysis of 19 RCTs with 2,495 patients, showing significantly lower mortality with vitamin D treatment.
19 meta analyses show significant improvements with vitamin D treatment for mortality1-14, mechanical ventilation1,6,7,12,15,16, ICU admission1,3,6,7,10,12,14-18, hospitalization5,12, severity2,4,6,11,19, and cases8,18,19.
Currently there are 122 vitamin D treatment for COVID-19 studies, showing 36% lower mortality [28‑43%], 19% lower ventilation [-3‑36%], 45% lower ICU admission [28‑58%], 19% lower hospitalization [9‑29%], and 17% fewer cases [9‑24%].
risk of death, 28.0% lower, OR 0.72, p = 0.04, RR approximated with OR.
risk of death, 43.0% lower, OR 0.57, p = 0.02, severe cases, RR approximated with OR.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
