*, now with p < 0.00000000001 from 418 studies, recognized in 46 countries.
No treatment is 100% effective. Protocols combine treatments. * >10% efficacy, ≥3 studies.
5,000+ studies for 104 treatments. c19hcq.org
Retrospective 766 hospitalized patients in DRC showing mortality reduced from 29% to 11%, and improvement at 30 days increased from 65% to 84%.
Mortality cox regression adjusted hazard ratio aHR 0.26, p < 0.001
Risk of no improvement adjusted odds ratio aOR 0.28, p < 0.001
Using marginal structural model analysis these risks became:
Mortality MSM adjusted odds ratio aOR 0.65, p = 0.166
Risk of no improvement MSM adjusted odds ratio aOR = 0.65, p = 0.132
Median age 46, 630 treated with CQ+AZ.
Although the 28% lower mortality is not statistically significant, it is consistent with the significant 26% lower mortality [22‑30%] from meta analysis of the 252 mortality results to date.
risk of death, 27.6% lower, RR 0.72, p = 0.17, treatment 69 of 630 (11.0%), control 28 of 96 (29.2%), NNT 5.5, adjusted per study, odds ratio converted to relative risk.
risk of no improvement, 25.8% better, RR 0.74, p = 0.13, adjusted per study, odds ratio converted to relative risk.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
