et al., J. Crit. Care, June 2020, 57:279-283, doi:10.1016/j.jcrc.2020.03.005, Epub Mar 10, 2020, Mar 2020
HCQ for COVID-19
1st treatment shown to reduce risk in
March 2020, now with p < 0.00000000001 from 424 studies, used in 59 countries.
No treatment is 100% effective. Protocols
combine treatments.
6,200+ studies for
200+ treatments. c19early.org

Review of six articles and 23 ongoing clinical trials in China recommending research and clinical use adhering to MEURI.
9 meta analyses show significant improvements with hydroxychloroquine for mortality1-4,
hospitalization1,
recovery5,
combined death/hospitalization/cases6,
cases7,8, and
viral clearance9.
Currently there are 38 HCQ for COVID-19 early treatment studies, showing 76% lower mortality [61‑85%], 67% lower ventilation [-710‑99%], 31% lower ICU admission [1‑53%], and 41% lower hospitalization [28‑51%].
