Collection of prognostic differential expression cuproptosis-related lncRNAs. (A) Volcano plot of differentially expressed lncRNAs. The downregulated lncRNAs are indicated by green spots, while the upregulated ones are indicated by red spots. (B) The HR (95% CI) and p-value of 15 collected prognosis- related lncRNAs. (C) The intersections of differentially expressed lncRNAs, prognosis-related lncRNAs, and cuproptosis-related lncRNAs were selected as the candidates. (D) LASSO coefficient profiles of 15 lncRNAs with p< 0.01. (E) Fivefold cross-validation results identified the optimal value of the penalty parameter λ. LASSO, least absolute shrinkage and selection operator; lncRNA, long non-coding RNA.
