12th treatment shown to reduce risk in January 2021
 
*, now known with p = 0.031 from 13 studies.
Lower risk for recovery and viral clearance.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments. c19early.org
