As baseline characteristics we analyzed age, gender, height, weight, body mass index, creatinine, hematocrit and platelet count. Creatinine values of the patients with renal replacement therapy (RRT) prior to transplantation were excluded from the calculation. For analysis the last available values directly before transplantation were included. Furthermore, the following clinical data were collected: underlying liver disease, Child-Turcotte-Pugh classification, MELD score uncorrected and corrected for hepatocellular carcinoma according to the regulation of the government [13] , incidence of hepatorenal syndrome directly before transplantation (according to the definition described by Arroyo and colleagues [16] and Salerno and colleagues [17] ), and diabetes mellitus, electively or high urgent listing, pretransplant location (home, normal hospital ward or ICU) and finally the need for pretransplant RRT.
