(a) Radiomics nomogram for the prediction of NAC sensitivity. Calibration curves of the nomogram model for the training set (b) and validation set (c). Calibration curves indicate the goodness-of fit of the nomogram. The 45 degree gray line indicates the ideal prediction and the dotted lines indicate the predictive performance of the nomogram. A better prediction accuracy of the nomogram is represented as the dotted lines approach the ideal line. ROC curves of various models in the training set (d) and the validation set (e). The nomogram and radiomics signatures show similar performance for prediction while the clinical model shows a poor performance.
