The Cox proportional hazard model for mortality identified sepsis (P = 0.011), postoperative RRT on ICU (P = 0.002), transfusion of more than 7 units of RBC (P = 0.045) and hepatorenal syndrome before transplantation (P = 0.016) as independent risk factors for mortality. Transfusion of more than 10 units of FFP, gender, use of marginal grafts, age, pretransplant diabetes mellitus, or postoperative bilirubin peak level, did not affect mortality (Table 4) .
