Development of a prognostic risk model based on IRRlncRNAs for BC patients. A-B Diagram for LASSO regression analysis based on prognostic IRRlncRNAs. C-D Kaplan–Meier plot revealed a notable difference in prognosis between the high- and low- risk groups (C: Training cohort; D: Test cohort). E-F Time-dependent ROC analysis represented 1-, 3-, and 5-year predictions based on 12 IRRlncRNAs risk model in BC samples (E: Training cohort; F: Test cohort). G-H The risk score curve (G: Training cohort; H: Test cohort). I-J Scatter plot of the relationship between survival status and risk score of each sample (I: Training cohort; J: Test cohort). Red dots mean the dead samples, while the green dots mean the alive samples. K-L Heatmap revealing the distribution of 12 IRRlncRNAs expression levels in risk groups (K: Training cohort; L: Test cohort)
