  1. Trajectory groups with lowest rate of 28-day mortality were considered as the reference in the logistic model. In univariate model, current trajectory group was adjusted. In multivariable model, current trajectory group, age, sex, SOFA, APS-III, vasopressin, ventilation, WBCs, BUN, creatinine, and respiratory rate were adjusted
  2. ORs odds ratios, CIs confidence intervals, SOFA Sequential Organ Failure Assessment, APS-III Acute Physiology Score III, WBCs white blood cells, BUN blood urea nitrogen, RR respiratory rate, HR heart rate, ROX respiratory rate-oxygenation
