Construction of the four-gene signature. (a) Forest plot of univariate Cox regression analysis showed that top 30 PRGs were associated with prognosis. (b) P values differed most significantly among the top 6 genes in the survival curve. (c) Selection of the tuning parameter (lambda) in the least absolute shrinkage and selection operator (LASSO) regression by 10-fold cross-validation based on minimum criteria for OS. (d) The coefficient of four genes of the signature
