A Coefficient profiles of the differentially expressed related genes and B Identification of the best parameter (lambda) in the LASSO. C Five genes retained to construct the optimal ERSRPS. D, G, J Kaplan–Meier analysis of overall survival. E, H, K Receiver operating characteristic (ROC) analysis of the ERSRPS in predicting the 1-, 3-, and 5-year overall survival. F, I, L Distribution plots of the risk score and overall survival status in the training, testing groups and GSE21257 cohort
