Crude model: No other covariates were adjusted. Minimally adjusted model: We adjusted age + sex. Fully adjusted model: We adjusted age + sex + cold ischemia time + blood loss + urine + liquid transfusion + blood transfusion + ischemia-reperfusion + anthepatic phase time + pediatric end-stage liver disease score. CVP: Central venous pressure; OR: Odds ratio; 95%CI: 95% confidence interval.
