Perioperative details after inverse probability of treatment weighting (IPTW).

HA: hemoadsorption group; stddiff: standardized difference; IV: Intravenous; CABG: Coronary artery bypass grafting; IABP: intraaortic balloon pump; ECMO: extracorporeal membrane oxygenation. Only one patient in the control group underwent concomitant surgery on pulmonary valve; so we did not analyze this variable using IPTW.
