Interaction between the albumin-bilirubin score and nutritional risk index in the prediction of post-hepatectomy liver failure

Table 3 Multiplicative interaction between the albumin-bilirubin score and nutritional risk index in post-hepatectomy liver failure

Variable	β	SE	Wald	P value	OR	95%CI
ALBI score	4.300	1.063	16.361	< 0.001	73.713	(9.175, 592.199)
NRI	4.077	1.064	14.698	< 0.001	58.990	(7.337, 474.297)
ALBI score × NRI	-1.031	1.432	0.519	0.471	0.357	(0.022, 5.889)

The confounding factors sex, history of hepatitis, total bilirubin, direct bilirubin, and international normalized ratio were adjusted for. ALBI: Albumin-bilirubin; CI: Confidence interval; NRI: Nutritional risk index; OR: Odds ratio; PHLF: Post-hepatectomy liver failure; SE: Standard error.
