Retrospective case control study of 3,100 healthcare workers in India showing lower cases with HCQ prophylaxis, and an inverse association between the number of HCQ doses taken and the risk of COVID-19 cases. Low risk population with no mortality and no severe cases.

Dev et al., 3/24/2021, retrospective, India, South Asia, peer-reviewed, 5 authors.

risk of COVID-19 case, 26.0% lower, RR 0.74, p = 0.003, treatment 260, control 499, any number of HCQ doses vs. no HCQ prophylaxis.

Effect extraction follows pre-specified rules prioritizing more serious outcomes. For an individual study the most serious outcome may have a smaller number of events and lower statistical signficance, however this provides the strongest evidence for the most serious outcomes when combining the results of many trials.

Elimination of COVID-19 is a race against viral evolution. No treatment, vaccine, or intervention is 100% available and effective for all current and future variants. Denying the efficacy of any method increases the risk of COVID-19 becoming endemic; and increases mortality, morbidity, and collateral damage. We do not provide medical advice.
