Identification of Cuproptosis-associated lncRNA prognostic features in hepatocellular carcinoma (HBV-HCC). (A) Sankey relationship diagram of cuproptosis genes and cuproptosis-associated Long non-coding RNAs (lncRNAs). (B, C) Least absolute shrinkage and selection operator (LASSO) regression screened of cuproptosis-related lncRNAs at the minimum point of cross-validation. (D) The forest plot shows the results of the multivariate Cox regression analysis. (E) Correlation of lncRNAs with cuproptosis-related genes in risk models. (F) Kaplan–Meier survival curves of overall survival of HBV-HCC patients between low- and high-risk groups in the train and internal validation sets, respectively. (G) Distribution and overall survival status of patient risk scores in the train and internal validation sets. (H) The expression heatmap of 3 cuproptosis-associated lncRNAs in the train sets and validation sets. Significant differences are indicated by *P < 0.05, **P < 0.01, and ***P < 0.001.
