Model performance evaluation and interpretation in the testing set. (a) ROC curve of the logistic regression model incorporating 7dDDE. (b) Decision Curve Analysis showing the net clinical benefit of the model across a range of high-risk thresholds compared to “treat-all” and “treat-none” strategies. (c) Clinical Impact Curve displaying the number of individuals identified as high-risk and the number of true positives across different thresholds. (d) Calibration curve generated via 100 bootstrap resamples. (e) SHAP plot ranking feature importance. (f) Nomogram constructed based on the top five variables.
