Survival and key secondary endpoint. (A) Depicts survival by randomization group. The tick marks show the censoring of data. (B) Depicts the distributions of rank by randomization group from the rank-based assessment of the key secondary endpoint, days alive, and free of mechanical ventilation at Day 60. Higher ranks correspond to better outcomes (i.e., fewer d on mechanical ventilation), and deaths were assigned the worst ranks in order of time of death. (C) Depicts the proportion of patients alive and off mechanical ventilation, alive on mechanical ventilation, alive with unknown ventilation status, withdrawn, or died, by randomization group over each study day from randomization through Day 60. CI = confidence interval; IQR = interquartile range; MSC = mesenchymal stromal cell.
