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. c19hcq.org
166 patients hospitalised with COVID-19, HCQ increased survival 1.4 - 1.8 times when patients admitted in early stages. Early is relative to hospital admission here - all patients were in relatively serious condition.
risk of death, 55.1% lower, RR 0.45, p = 0.002, treatment 27 of 123 (22.0%), control 21 of 43 (48.8%), NNT 3.7.

Hydroxychloroquine has shown in vitro activity against SARS-CoV-2. Here we present an observational study. We analysed data from 164 patients admitted to our hospital diagnosed with COVID-19. Hydroxychloroquine treatment was associated with an increase in the mean cumulative survival.
