Identification of the prognostic CDRLRs and construction of prognostic risk model. A Protein–protein interactions among CDRGs based on STRING database. B The sankey relation between CDRGs and CDRLRs. C Forest plot showing univariate Cox regression analysis of prognosis-related CDRLRs (p < 0.05). D The LASSO regression coefficient spectrum. E Cross-validation of parameter selection in the LASSO model. F Heatmap of the correlation between CDRGs and 4 CDRLRs (*p < 0.05, **p < 0.01, ***p < 0.001)
