故PV增宽、年龄增大是判断肝硬化患者EGVB的重要指标，而SV增宽是其保护性因素。

Results displaied age (OR=1.2, 95%CI 1.1-1.3, P=0.006) and width of inner diameter of portal (OR=4.7, 95%CI 1.5-14.6, P=0.008) were independent risk factors for EGVB. However, the width of inner diameter of splenetic vein (OR=0.4, 95%CI 0.2-0.9, P=0.036) was protective factor for EGVB.

结果显示年龄、PV增宽是EGVB的危险因素(P=0.006、0.008)，OR值为1.179、4.649，95%CI值为(1.049， 1.324)，(1.487， 14.599)，而SV增宽是EGVB的保护性因素(P=0.036)，DR值为0.423，95%CI值为(0.190，0.944)。
