Data are presented as mean ± SD with ranges (min-max) or median with IQR (interquartile ranges) when the distribution is skewed for continuous variables. Categorical variables are presented as counts (percentages). BMI: Body mass index; Na: Sodium; ALT: Alanine aminotransferase; GGT: Gamma-glutamyl transferase; CRP: C-reactive protein; ET-DRI: Eurotransplant donor risk index; CIT: Cold ischemia time.
