Retrospective 247 mechanically ventilated patients showing lower mortality with HCQ, but not statistically significant on multiple Cox regression.
The paper gives the p value for multiple Cox (0.46) and simple Cox (0.02), but does not specify the adjusted risk values.
Lambermont et al., 11/28/2020, retrospective, Belgium, Europe, peer-reviewed, 15 authors.
risk of death, 32.3% lower, RR 0.68, p = 0.46, treatment 97 of 225 (43.1%), control 14 of 22 (63.6%), adjusted per study.
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.
