Prediction of the Factors Influencing the Shengjing Classification of Portal Vein Thrombosis after Splenectomy for Portal Hypertension in Cirrhosis: A Single-Center Retrospective Case-Control Study

Table 2

COX regression analysis results of the Shengjing classification.

Variables		SE	Wald		HR	HR 95% CI
						Lower limit	Upper limit
Shengjing classification I/II	-1.675	0.649	6.656	0.010^a	0.187	0.052	0.669
Shengjing classification II/III	-1.492	0.595	6.293	0.012^a	0.225	0.070	0.722

^a indicates that the difference in mortality risk between the Shengjing classification groups was statistically significant. HR: relative risk.
