Screening GRGs to construct a prognostic model and verifying its feasibility. A Univariate Cox regression analysis to select prognosis related GRGs. B Predictive accuracy of C-index detection prognostic model. C Lasso regression analysis to select the best parameters. D The association with regression coefficients and log-transformed lambda. E Kaplan–Meier curves were plotted in the entire TCGA cohort after distinguishing between high- and low-risk groups according to the model. F The ROC analysis at 1,3,5 years of overall survival in the entire TCGA cohort. G Kaplan–Meier curves were plotted in the tissues from the first affiliated Hospital of Nanjing Medical University after distinguishing between high- and low-risk groups according to the model. H The ROC analysis at 1,3,5 years of overall survival in the PC patient tissues
