Retrospective analysis of retirement homes, HCQ+AZ >= 3 days mortality OR 0.37,
p=0.02. 1690 elderly residents (mean age 83), 226 infected residents, 116 treated with HCQ+AZ >= 3 days.
Detection via mass screening also showed significant improvements (16.9% vs. 40.6%, OR 0.20,
p=0.001), suggesting that earlier detection and treatment is more successful.
Ly et al., 8/21/2020, retrospective, France, Europe, peer-reviewed, mean age 83.0, 21 authors, dosage 200mg tid days 1-10.
risk of death, 55.6% lower, RR 0.44, p = 0.02, treatment 18 of 116 (15.5%), control 29 of 110 (26.4%), adjusted per study, odds ratio converted to relative risk.
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.
