"A total of 18 patients died in the hospital during the trial (5 patients assigned to receive hydroxychloroquine plus azithromycin, 7 in the hydroxychloroquine-alone group, and 6 in the control group). There were no significant between-group differences with regard to the secondary outcomes of thromboembolic complications or acute kidney injury within 15 days, either in the prespecified analyses (Table 2) or in post hoc analyses that accounted for the competing risk of death (Table S11)."
