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.
No treatment is 100% effective. Protocols combine treatments.
5,100+ studies for 109 treatments. c19hcq.org
Small RCT on very late stage use of HCQ, with 48% on oxygen at baseline. 67 HCQ patients, 61 control. Baseline states were not comparable - 82% more HCQ patients had the highest severity at baseline, there was 32% more male HCQ patients, and 44% more control patients used AZ. The HCQ group also had significantly more patients with cerebrovascular disease, cardiovascular disease (non-hypertension), renal disease (non-dialysis), and a history of organ transplants.
This study is excluded in the after exclusion results of meta analysis: very late stage, >50% on oxygen/ventilation at baseline.
risk of death, 6.0% higher, RR 1.06, p = 1.00, treatment 7 of 67 (10.4%), control 6 of 61 (9.8%).
risk of mechanical ventilation, 51.7% higher, RR 1.52, p = 0.72, treatment 5 of 67 (7.5%), control 3 of 61 (4.9%).
risk of ICU admission, 173.1% higher, RR 2.73, p = 0.13, treatment 9 of 67 (13.4%), control 3 of 61 (4.9%).
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
