Clinical evaluation of the lncRNA pair-based risk model. (A, B) Forest plots from univariate and multivariate Cox regression analyses, demonstrating the prognostic significance of the risk score. (C) Comparison of ROC curves between the risk model and clinicopathological features, confirming the superior predictive performance of the risk score. (D, E, F) Association between risk score and clinical parameters, including clinical stage, T stage, and N stage. (G) Nomogram for predicting 1-, 3-, and 5-year survival rates in TNBC patients. (H, I) C-index and calibration curves, assessing the accuracy and calibration of the nomogram. (J) Decision curve analysis (DCA), comparing the clinical benefit of different models: Nomogram, Risk score, “All” strategy, and “None” strategy.
