Vitamin D for COVID-19
8th treatment shown to reduce risk in October 2020
 
*, now known with p < 0.00000000001 from 120 studies, recognized in 8 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,100+ studies for 60+ treatments. c19early.org
Analysis of 239 consecutive diabetic patients, 97 taking vitamin D supplements, showing significantly higher vitamin D levels in supplemented patients. There was no statistically significant difference in cases based on supplementation, with only 3 cases total.
Although the 27% fewer cases is not statistically significant, it is consistent with the significant 17% fewer cases [9‑24%] from meta analysis of the 30 cases results to date.
This is the 52nd of 120 COVID-19 controlled studies for vitamin D, which collectively show efficacy with p<0.0000000001 (1 in 248 sextillion).
29 studies are RCTs, which show efficacy with p=0.0000024.
This study is excluded in the after exclusion results of meta analysis: very few events; unadjusted results with no group details; minimal details provided.
risk of case, 26.8% lower, RR 0.73, p = 1.00, treatment 1 of 97 (1.0%), control 2 of 142 (1.4%), NNT 265.
