  2. aAs this parameter was included in SOFA score calculation, it was not entered into the multivariate analysis
  3. bWe conducted Spearman correlation analyses for continuous variables and selected one member of each pair of correlated variables (r > 0.3 and p < 0.05) to include in the logistic regression model to avoid multicollinearity
