Numerical variables are presented as median with limits of the interquartile range, categorical variables as number (percentage). * Acute physiology and chronic health evaluation, ** Length of stay. Missing values ≤10% were not reported, no missing values >10% were observed. Statistical Tests: Independent groups A vs. B1 Mann–Whitney Test for numerical variables, Pearson’s Chi2 for categorical variables. Matched cohort A vs. B2: Wilcoxon Test for numerical variables, McNemar’s Test for categorical variables.
