DCA curves for the predictive model. (A) Training cohort. (B) Validation cohort. The X-axis represents the high-risk threshold, which is the risk required to drive a specific treatment (ranging from 0 to 1). The Y-axis represents the standardized net benefit, which shows the net benefit across a range of threshold probabilities. The red line represents the predictive model, the gray line represents the “All” strategy (treating all patients), and the black line represents the “None” strategy (treating no patients)
