ALT, alanine aminotransferase; AST, aspartate aminotransferase; BMI, body‐mass index; CIT, cold ischemia time; DBD, donation after brain death; DCD, donation after circulatory death; DRI, donor risk index; dWIT, donor warm ischemia time; ET‐DRI, Eurotransplant donor risk index; γGT, γ‐glutamyltransferase.

^adWIT is defined as the time from withdrawal of mechanical support until the start of in situ cold perfusion.

^bCIT is defined as the time from in situ cold perfusion until the start of machine perfusion.

^cDonor hepatectomy time is defined as the time from in situ cold perfusion until the time of hepatectomy.
