Data are presented as n (%) categorical variables and median (interquartile range) for nonparametric variables. ARDS, acute respiratory distress syndrome; AMI, acute myocardial infarction; RBC, red blood cell; PLT, platelet count; FFP, fresh frozen plasma; Cry, cryoprecipitate; AKI, acute kidney injury was defined by KDIGO criteria; ECMO, extracorporeal membrane oxygenation.
