Evaluation of prognosis prediction ability of cuproptosis-related lncRNAs prognostic signature. Risk scores in the high and low-risk groups for the prognostic signature in COAD in the training set (A) and validation set (B). Survival status of patients with COAD in high- and low-risk groups in the training set (C) and validation set (D). Expression of the 10 cuproptosis-related lncRNAs in COAD in the training set (E) and validation set (F). Survival analysis of the high-risk group and the low-risk group in the training set (G) and validation set (H) based on the TCGA dataset. ROC curve of the prognostic signature in the training (I), validation (J), and entire (K) sets. ROC curve, receiver operating characteristics curve; AUC, area under the curve; P<0.05, statistically significant.
