The decision curve analysis in this study. The decision curve analysis showed that using the CT-based rad-score to predict pCR added benefit than treating either all or no patients did when the threshold probability was between 0 and 1 (A) and using the CT-MRI-based integrated model gained more benefit when comparing with the MRI-based rad-score (B). The y-axis measured the net benefit. The x-axis represented the threshold probability. The red line represented the radiomic model. The grey line represented the assumption that all patients achieved pCR. The black line represented the hypothesis that no patients achieved pCR
