Kaplan–Meier curves of patients stratified by three-category I-score, two-category I-score, and two-category I-score and TNM stage. Compared with a low I-score (three-category), a high I-score is associated with superior DFS in discovery cohort (a P = 0.005) and validation cohort (b P = 0.029), whereas an intermediate I-score is not significantly associated with DFS in both cohorts (P > 0.050). Compared with a low I-score (two-category), a high I-score is associated with significantly superior DFS, in both discovery cohort (c P = 0.004) and validation cohort (d P = 0.001). The two-category I-score and TNM stage are significantly associated with DFS in both discovery cohort (e P < 0.001) and validation cohort (f P < 0.001). The unadjusted HRs, corresponding 95% confidence intervals, and P-values are determined by univariable Cox regression models. DFS disease-free survival. HR hazard ratio. Data in parentheses are 95% confidence intervals
