12th treatment shown to reduce risk in January 2021, now with p = 0.00016 from 14 studies.
No treatment is 100% effective. Protocols combine treatments.
5,100+ studies for 112 treatments. c19early.org
Significantly lower risk is seen for ventilation, hospitalization, recovery, cases, and viral clearance. 11 studies from 10 independent teams in 8 countries show significant benefit.
Meta analysis using the most serious outcome reported shows 43% [24‑57%] lower risk. Results are similar for Randomized Controlled Trials and higher quality studies. Early treatment is more effective than late treatment.
Results are very robust — in exclusion sensitivity analysis 11 of 14 studies must be excluded to avoid finding statistically significant efficacy in pooled analysis.
No treatment is 100% effective. Protocols combine safe and effective options with individual risk/benefit analysis and monitoring. The quality of non-prescription supplements varies widely1,2. All data and sources to reproduce this analysis are in the appendix.
Other meta analyses show significant improvements with nigella sativa for mortality3,4 and viral clearance4.
2 meta analyses show significant improvements with nigella sativa for mortality1,2 and viral clearance2.
