*, platelet component was removed from SOFA score. AUC, area under the ROC curves; CI, confidence interval; DIC, disseminated intravascular coagulation; ECMO, extracorporeal membrane oxygenation; PT, prothrombin time; SAPS, simplified acute physiology score; SOFA, sequential organ failure assessment.
