Varices	2.23 (0.78-4.18)	0.162
Ascites	2.58 (1.21-6.41)	0.079
Hepatic hydrothorax	3.14 (0.33-5.22)	0.198
Abdominal pain	2.22 (0.67-5.21)	0.134
Splenectomy	1.22 (0.56-3.37)	0.132	4.67 (2.59-7.44)	0.017
Child-Pugh score	3.23 (0.89-6.32)	0.147
Baseline MELD score	2.36 (0.49-5.41)	0.078
CTPV score	7.70 (1.78-13.92)	0.012	9.22 (4.78-13.45)	0.009

Only variables with a P value < 0.2 in the univariate analysis are shown. Variables selected into the univariate analysis were age, gender, etiology of cirrhosis, manifestations of liver disease, splenectomy, Child-Pugh score, baseline model of end-stage liver diseases score, laboratory tests, and cavernous transformation of the portal vein score. MELD: Model of end-stage liver diseases; CTPV: Cavernous transformation of the portal vein; CI: Confidence interval; HR: Hazard ratio.
