Model scope, verification and limitations
Source population
Development: First Medical Center, Chinese PLA General Hospital (223,415 records). Evaluation: Henan Provincial People's Hospital (48,719) and Nanfang Hospital, Southern Medical University (37,568).
Technical verification
Browser implementation compared with the locked native model using source-record inputs and split-boundary cases. Full results accompany the figure package.
Interpretation
Multicentre retrospective prediction model study. Original missing-data handling and selected source codes require verification. Cross-hospital calibration and the Henan CAD coding anomaly limit clinical interpretation. Automatic high/low research groups use the development out-of-fold 95th-percentile cutoff (probability 0.006778159165645454). The percentage selected varies across hospitals. Input-based clinical review topics include information checks and guideline sources.
