The cuproptosis-related lncRNA risk score was identified as an independent prognostic factor for patients with BC. Univariate and multivariate Cox regression analyses of the signature in the training (A, C) and validation (B, D) sets. Clustering analysis heatmaps indicate the expression levels of the nine identified cuproptosis-related lncRNAs and the clinicopathological characters of the respective patients with BC in training (E) and validation (F) groups (stage, AJCC tumor stage I/II/III/IV). lncRNA, long non-coding RNA; BC, breast cancer; AJCC, American Joint Committee on Cancer.
