Mortality Risk Factors among Hospitalized COVID-19 Patients in a Major Referral Center in Iran
Retrospective 459 patients in Iran 93% using HCQ, showing HCQ mortality RR 0.45, p = 0.028. HCQ was the only antiviral that showed a significant difference. Small number of control patients and subject to confounding by indication. Average admission delay 5.72 days.
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.
