Radiomics nomogram to estimate iDFS for patients with triple-negative breast cancers and its discrimination performance. (a) The radiomics nomogram was developed by incorporating pN stage and radiomics score. b−e. Calibration curves of the nomogram for the estimation of 1-year (b), 2-year (c), 5-year (d), and 8-year (e) iDFS in the training cohort. The diagonal line represents a perfect match between the predicted (x-axis) and actual (y-axis) probabilities, and the colored line represents the predictive performance of the nomogram. The closeness between the two lines indicates the predictive accuracy of the nomogram.
