HCQ for COVID-19
1st treatment shown to reduce risk in March 2020
 
*, now known with p < 0.00000000001 from 422 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.
3,900+ studies for 60+ treatments. c19hcq.org
PSM retrospective 29 hospitals in Saudi Arabia, finding lower mortality with HCQ, without reaching statistical significance (described by authors as "no impact").
Study covers convalescent plasma, remdesivir, favipiravir, and HCQ.
risk of death, 50.0% lower, RR 0.50, p = 0.18, treatment 6 of 161 (3.7%), control 50 of 653 (7.7%), NNT 25, adjusted per study, odds ratio converted to relative risk, propensity score matching, multivariable.
risk of progression, 37.0% lower, RR 0.63, p = 0.21, treatment 16 of 161 (9.9%), control 100 of 653 (15.3%), NNT 19, adjusted per study, odds ratio converted to relative risk, AKI, ARDS, multi-organ failure, or mortality, propensity score matching, multivariable.
ICU time, 9.2% lower, relative time 0.91, p = 0.66, treatment 22, control 169, propensity score matching.
hospitalization time, 3.0% higher, relative time 1.03, p = 0.69, treatment 161, control 653, propensity score matching.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
