The prognostic value of four cuproptosis-related lncRNAs in the validation set and all samples. The expression levels of four lncRNAs in the (A) validation set and (B) all samples. The change from blue to red means the rise of expression. The distribution of the risk scores in the (C) validation set and (D) all samples. The correlation of risk scores and survival status in the (E) validation set and (F) all samples. Kaplan–Meier overall survival curve of samples in the (G) validation set and (H) all samples. ROC curves of the risk signature in the (I) validation set and (J) all samples. The Univariate Cox regression analysis of risk score and other clinical features in the (K) validation set and (L) all samples. The Multivariate Cox regression analysis of risk score and other clinical features in the (M) validation set and (N) all samples.
