Figure 3. Predictive performance of the DRLs signature and establishment of clinicopathologic nomogram. ROC curves of the DRLs signature for predicting 1-, 3-, and 5-year OS in the training (A), testing (B), and TCGA cohorts (C). (D) ROC curves of the DRLs risk signature and clinical parameters for predicting 3-year OS in the TCGA cohort. (E) C-index of the DRLs signature and clinical parameters in the TCGA cohort. Univariate (F) and Multivariate (G) Cox regression analyses of the DRLs signature and clinical parameters. (H) Development of a prognostic nomogram for predicting patient survival in HCC. (I) Calibration curve of the prognostic nomogram. Abbreviations: DRLs: disulfidptosis-related lncRNAs; OS: overall survival; C-index: concordance index.
