The predictive performance of the radiomics signature for each patient in training (a) and validation (b) sets (95% CI, 95% confidence interval; AUC, area under curve). The radiomics signature for each patient in training (c) and validation (d) sets. Blue dots show signature values for non-pGR patients, while red triangles indicate values for pGR patients. The dotted line shows the best cutoff values calculated by Youden test, which is − 0.251 for the training dataset
