Decision curves of the nomogram predicting OS in training cohort (A) and validation cohort (B). Decision curves of the nomogram predicting CSS in training cohort (C) and validation cohort (D). The y-axis represents the net benefit, and the x-axis represents the threshold probability. The purple line indicates that no patients have died, and the blue line indicates that all patients have died. When the threshold probability is between 20 and 60%, the net benefit of the model exceeds all deaths or no deaths
