Definition of abbreviations: CI = confidence interval; mSOFA = modified Sequential Organ Failure Assessment; PEEP = positive end-expiratory pressure; sST2 = soluble suppression of tumorigenicity-2.

^*Model adjusted for baseline covariates. For continuous variables, hazard ratios are for a 1-unit increase in the variable.
