The Decision Curves Analysis curve for the nomogram of DMFS in the training cohort (A) and validation cohort (B).

Notes: In the decision curve analysis curve, the horizontal axis represents the threshold value, which is the reference probability of whether a patient receives treatment. The vertical axis represents the net benefit rate after disadvantages are subtracted from the advantages. Under the same threshold probability, a larger net benefit implies that patients can obtain the maximum benefit using the diagnosis model. A larger net benefit in the DCA graph corresponds to a higher value of the diagnosis model.
