Risk Category Definition:

The model outputs a binary risk category using the optimal probability cutoff determined by the Youden index:
• LOW risk:Predicted probability < cutoff
• HIGH risk:Predicted probability ≥ cutoff

• Responsibility

Predictions are generated by a machine learning model trained on multicenter clinical data and should not replace professional medical judgment.

All treatment decisions must be made by qualified physicians in conjunction with comprehensive clinical evaluation.
