Notes: (1) The outcomes are presented as no. (%) unless specified differently. (2) p-Values refer to Chi-square test/ANOVA and the letters denote the columns with which a statistically significant pairwise comparison exists (Bonferroni's method).
Abbreviations and symbols: BMI = body mass index, IQR = interquartile range, no. = number, O2 = oxygen, ↑ = increasing, ARDS = acute respiratory distress syndrome, ICU = intensive care unit, AKI = acute kidney injury, RRT = renal replacement therapy.
