Outcomes of patients with COVID-19 in the Intensive Care Unit in Mexico: A multicenter observational study
Outcomes of patients with COVID-19 in the Intensive Care Unit in Mexico: A multicenter observational study
Retrospective 164 ICU patients in Mexico showing 32% lower mortality with HCQ+AZ and 37% lower with CQ.HCQ+AZ vs. neither HCQ or CQ relative risk RR 0.68, p = 0.03
CQ vs. neither HCQ or CQ relative risk RR 0.63, p = 0.02
HCQ+AZ or CQ vs. neither relative risk RR 0.65, p = 0.006
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.
