Values are presented as patient number (%) or median [interquartiles]. Abbreviations: ARDS acute respiratory distress syndrome, AKI acute kidney injury, A.fib atrial fibrillation. Composite complication: P = 0.0324 between Group Low vs. Group Cutoff. ARDS: P = 0.0432 between Group Low vs. Group Cutoff. Bronchopleural fistular: P = 0.0339 between Group Cutoff vs. Group High. Bonferroni correction was done.
