HCQ for COVID-19

1st treatment shown to reduce risk in March 2020, now with p < 0.00000000001 from 423 studies, used in 59 countries.

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

No treatment is 100% effective. Protocols combine treatments.

5,700+ studies for 141 treatments. c19hcq.org

Analysis of the Fiolet meta analysis and correction of bias evaluation, showing HCQ RR 0.45 [0.31-0.59], and HCQ+AZ RR 0.34 [0.06-0.61].

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%].

Objective: To analyze the impact of study selection on the results of a recently published meta-analysis of the efficacy of hydroxychloroquine (HCQ) and hydroxychloroquine plus azithromycin (AZI) in Covid-19 patients. Methods: 31 studies were reviewed looking for critical bias. Combined hazard ratios and confidence intervals were calculated for both treatments using a fixed effects size model and a random effects model. Quantitative analysis regarding the toxicity of the association HCQ plus AZI is made. Results: Meta-analyses performed on the 11 studies we deem critically unbiased show a mortality reduction of 55% for HCQ and 66% for HCQ plus AZI. For both treatments, our meta-analysis indicates a significant efficacy in reducing mortality in hospitalized Covid-19 patients.
