Kaplan-Meier estimates of all-cause mortality by day 28 and by day 60

(A) 28-day all-cause mortality. (B) 60-day all-cause mortality. All-cause mortality includes deaths potentially related with COVID-19 and deaths attributed to adverse events. The numbers at risk at days 27 and 59 represent the numbers of participants with available data at days 28 and 60, respectively. The data in parentheses below the curve represent the numbers of deaths that occurred during the interval until the next timepoint. HRs and 95% CIs were calculated using a Cox proportional hazard regression model adjusted for treatment group, age (<65 years vs ≥65 years), and geographical region (USA vs the rest of the world); unstratified. p values were calculated from an unstratified log-rank test. HR=hazard ratio.
