  1. Data are presented as the median and interquartile range or as numbers (percentages)
  2. P values are analyzed using the Chi-square (Fisher’s exact) test or the Kruskal–Wallis test
  3. ECMO extracorporeal membrane oxygenation, CRRT continuous renal replacement therapy, ICU intensive care unit
