Retrospective 607 patients reporting results for early outpatient HCQ use with mortality odds ratio OR 0.092 [0.022-0.381],
p = 0.001 (65 patients), and for hospital use, mortality odds ratio OR 0.737 [0.38-1.41],
p = 0.36 (558 patients). Median age 69.

risk of death, 20.3% lower, RR 0.80, p = 0.36, treatment 127 of 558 (22.8%), control 14 of 49 (28.6%), adjusted per study, odds ratio converted to relative risk.
outpatient use, 88.0% lower, RR 0.12, p = 0.001, treatment 2 of 65 (3.1%), control 139 of 542 (25.6%), 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.
