Covid Analysis (Preprint) (meta analysis) Vitamin D for COVID-19: real-time meta analysis of 148 studies • Statistically significant improvements are seen in treatment studies for mortality, ventilation, ICU admission, hospitalization, and cases. 28 studies from 26 independent teams in 12 different countries show statistically significant improvements in isolation (22 for the most serious outcome). • Random effects meta-analysis with pooled effects using the most serious outcome reported shows 86% [70‑93%] and 43% [35‑51%] improvement for early treatment and for all studies. Results are similar after restriction to 49 peer-reviewed studies: 84% [68‑92%] and 44% [35‑5
