	B	S.E.	Wald	Sig.	Exp(B)	OR 95% C.I
Pre-ammonia	−0.29	0.100	5.276	0.022	0.795	(0.654, 0.967)
Pre-bilirubin	0.019	0.009	4.255	0.039	1.019	(1.001, 1.038)
Constant	2.857	4.331	0.435	0.509	17.414

Factors were included according to the results of univariate analysis of PDI with the P value <0.05 (preoperative ammonia, total bilirubin, creatinine, PELD, INR).
