Predictive performance of the radiomics score. We constructed and validated a radiomics-based model. Subgroup analysis was performed. a A radiomics-based nomogram based on multivariate analysis to estimate the DFS of LABC patients. b Calibration curves of the radiomics nomogram showed good agreement between the estimated and actual survival time. c Time-dependent ROC showed good predictive accuracy at 1,5-year timepoint in both cohorts. d DCA analysis was performed in all three models and showed that radiomics-based nomogram outperformed the TNM model and clinical model. e–i Kaplan–Meier survival analysis was in non-pCR and HR-positive subgroups in both cohorts. Radiomics score stratified tumor recurrence risk in non-pCR subgroup and HR-positive subgroup. Forest plot was shown based on training cohort
