	Whole liver viable a prior to splitting	Details	Partial liver viable a at 24 h after splitting	Details
Liver 1	Yes	Lactate 0.93 mmol/L Bile production pH 7.313	LLSG: Yes	Lactate 0.63 mmol/L Bile production pH 7.395
			ERG: Yes	Lactate 1.03 mmol/L Bile production pH 7.394
Liver 2	Yes	Lactate 0.74 mmol/L Bile production pH 7.303	LLSG: Yes	Lactate 0.83 mmol/L Bile production pH 7.552
			ERG: Yes	Lactate 0.69 mmol/L Bile production pH 7.445

Abbreviations: ERG, extended right graft; LLSG, left lateral segment graft.

^a Viable according to the criteria proposed by the VITTAL clinical trial (lactate ≤ 2.5 mmol/L, and two or more of: bile production, pH ≥ 7.30, glucose metabolism, hepatic arterial flow ≥ 150 ml/min, and portal vein flow ≥ 500 ml/min, or homogeneous perfusion). ⁸
