Postoperative morbidity adversely impacts oncological prognosis after curative resection for hilar cholangiocarcinoma

Table 3 Univariable and multivariable logistic regression analyses of risk factors associated with postoperative morbidity following curative resection for hilar cholangiocarcinoma

Variables	Multivariable analyses1
	P value	OR (95%CI)
Obesity	0.023	3.694 (1.197-11.394)
Diabetes mellitus	0.036	3.395 (1.082-10.651)
Cirrhosis	0.017	2.867 (1.207-6.810)
Preoperative CA19-9 > 150 U/L	0.155	1.493 (0.859-2.593)
Intraoperative blood loss > 500 mL	0.016	2.240 (1.162-4.318)

¹Factors with P < 0.1 in Table 2 were applied to multiple logistic regression model.

CA19-9: Carbohydrate antigen 19-9; CI: Confidence interval; OR: Odds ratio.
