Gene cluster and prognostic risk label in Co-PCa: a Co-PCa patients were divided into three gene clusters on the basis of 64 DEGs via a consensus clustering algorithm. b Differences in PFS among the three gene clusters. c Heatmap of clinicopathological features and expression of DEGs. d DRG expression levels in the 3 gene clusters. e, f Selection of the LASSO model; the simulation parameters were set to 1000, tenfold cross-validation was selected, and 4 risk genes were screened. g–i Differences in PFS between the low-risk group and the high-risk group in the training group, testing group, and external testing group. j–l ROC curve for predicting the 1-, 3-, and 5-year PFS of patients in the training group, testing group, and external testing group. m Risk score distribution in two DRG clusters. n Risk score distribution in three gene clusters. o Connections among the DRG cluster, gene cluster, and risk group
