HCQ for COVID-19
1st treatment shown to reduce risk in March 2020
*, now known with p < 0.00000000001 from 421 studies, recognized in 42 countries.
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.
Retrospective 811 hospitalized COVID+ patients in Saudi Arabia, showing higher mortality with HCQ treatment in unadjusted results subject to confounding by indication.
This study is excluded in the after exclusion results of meta analysis: unadjusted results with no group details; substantial unadjusted confounding by indication likely.
risk of death, 34.6% higher, RR 1.35, p = 0.46, treatment 20 of 466 (4.3%), control 11 of 345 (3.2%).
