HCQ for COVID-19

1st treatment shown to reduce risk in March 2020

^*, now with p < 0.00000000001 from 411 studies, recognized in 46 countries.

Lower risk for mortality, hospitalization, progression, recovery, cases, and viral clearance.

No treatment is 100% effective. Protocols combine treatments. ^* >10% efficacy, ≥3 studies.

4,500+ studies for 81 treatments. c19hcq.org

Estimated 214 participant HCQ + bromhexine prophylaxis RCT with results not reported over 3 years after estimated completion.

38 HCQ RCTs have results missing long after expected1-38
The trials report a total of 25,399 patients, with 12 trials having actual enrollment of 8,139, and the remainder estimated.
