A risk model for outcome prediction. A The distribution of the risk scores for each patient. B the distributions of the overall survival status for every patient. C The heatmap of 6 SRlncRNAs expression. D Kaplan–Meier curves for the overall survival of patients in the high- and low-risk groups. E Accuracy of the risk signature in predicting 3-, 5-, and 8-year ROC curves. F PCA of all examined genes expression. G PCA of all SRGs expression. H PCA of SRlncRNAs expression. I PCA of the prognostic 6 SRlncRNAs signature. TNBC triple-negative breast cancer, SRGs stemness-related genes, SRlncRNAs stemness-related lncRNAs, PCA Principal components analysis
