Hydroxychloroquine with or without azithromycin and in-hospital mortality or discharge in patients hospitalized for COVID-19 infection: a cohort study of 4,642 in-patients in France
Retrospective of 4,642 hospitalized patients in France showing significantly faster discharge with HCQ and HCQ+AZ. No significant effect is seen on 28-day mortality, however many more control patients are still in hospital at 28 days. Other studies show faster resolution for HCQ, suggesting there will be a significant improvement when extending past 28 days. Hopefully authors will extend the analysis. Note that the median age is higher in the group not treated with HCQ or AZ.For other issues with the adjustments see [1]. Also see the analysis here [2].
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.
