¹Corresponds to a Wilcoxon Mann-Whitney test.

Data are summarized as median (IQR) or n (%), where n = available sample size. CPK: Creatine phosphokinase, Pro-BNP: N-terminal pro- brain natriuretic peptide; ECMO: Extracorporeal membrane oxygenation; IABP: Intraaortic balloon pump; RRT: Renal replacement therapy; NIPPV: Non invasive positive pressure ventilation.
