Figure 5. Kaplan-Meier survival analysis for PNI. During
long-term follow-up period (median, 50 months), patients group with PNI
≤40 had significantly worse survival than patients with PNI
>40 (p <0.001). Mean survival time for PNI
≤40 and PNI >40 was 54.033±7.277 and 79.521±2.607,
respectively) (p <0.001).
