HCQ for COVID-19
1st treatment shown to reduce risk in March 2020, now with p < 0.00000000001 from 419 studies, recognized in 46 countries.
Lower risk for mortality, hospitalization, progression, recovery, cases, and viral clearance.
No treatment is 100% effective. Protocols combine treatments.
5,100+ studies for 109 treatments. c19hcq.org
Early results from a very small trial, reported within the application for a later trial. Very minimal details are provided, but we include this as the earliest published results. For COVID-19 patients with pneumonia the viral negative conversion rate was 50% (5/10) with CQ versus 20% (3/15) with lopinavir/ritonavir.
This study is excluded in the after exclusion results of meta analysis: minimal details provided.
