Cuproptosis-related long non-coding RNAs model that effectively predicts prognosis in hepatocellular carcinoma

Figure 3 Internal validation of cuproptosis-related long-chain non-coding RNA signature (CupRLSig) model for determination of overall survival in training, test, and entire The Cancer Genome Atlas-Live Hepatocellular Carcinoma groups. A-C: Kaplan-Meier survival curves in the high- and low-risk groups stratified by median CupRLSig risk scores for overall survival in the training set (A), test set (B), and entire The Cancer Genome Atlas-Live Hepatocellular Carcinoma (TCGA-LIHC) dataset (C); P values were determined using the log-rank test; D-F: Risk curves were based on the risk score for each sample in the training (D), test (E), and entire TCGA-LIHC (F) sets, where red and blue dots indicate high- and low-risk samples, respectively; G-I: The scatter plot was based on the survival status of each sample from the training (G), test (H), and entire TCGA-LIHC (I) sets, where red and blue dots indicate death and survival, respectively; J-L: Heatmaps detailing the expression levels of the three cuproptosis-related long-chain non-coding RNA (lncRNA) signature (CupRLSig) lncRNAs in each group.
