Predictive value depicted by the proposed risk model in comparison to clinicopathologic factors and subgroup analysis. The findings of the ROC curves of prognostic accuracy were used for comparing the risk score with clinicopathologic factors in the entire set for A 1 year, B 3 years, and C 5 year. D C-index was employed for comparing the prognostic accuracy of clinical factors and risk score. E Decision curves depicted the clinical advantages described by the risk model using the entire cohort. F Univariate and G multivariate regression analysis of risk scores in the entire set. H Subgroup analysis of the K–M survival curve depends on factors like gender, age, histopathological grade, and clinical stage
