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

Figure 2 Construction of the cuproptosis-related long-chain non-coding RNA signature (CupRLSig) model. A: Sankey diagram showing the associations between cuproptosis-related long-chain non-coding RNAs (lncRNAs) and mRNAs; B: Forest plot showing 27 LncRNAs with hazard ratios (95% confidence intervals) and P values for association with HCC prognosis based on univariate Cox proportional-hazards analysis; C: Lasso coefficient profiles; D: Selection of the tuning parameter (lambda) in the Lasso model by ten-fold cross-validation based on minimum criteria for overall survival; E: Heatmap showing the correlations of the three lncRNAs incorporated into the cuproptosis-related long-chain non-coding RNA signature model (CupRLSig) model and 19 cuproptosis-related genes. ^aP < 0.05; ^bP < 0.01; ^cP < 0.001.
