| Metric | Value |
|--------|-------|
| Accuracy | 82.4% |
| Clinical Weight | 91% |
| X-ray Weight | 9% |
| Test Set Size | 46 aligned patients |
| True Negatives | 22 |
| False Positives | 3 |
| False Negatives | 4 |
| True Positives | 17 |
### Feature Importance (Clinical Model)
| Feature | Importance |
|---------|------------|
| Pain Scale | **58.7%** |
| Heart Rate | 10.8% |
| Age | 10.2% |
| Systolic BP | 10.2% |
| Diastolic BP | 10.1% |
**Interpretation:** Pain scale dominates prediction, which aligns with clinical expectation that patient-reported pain is the strongest indicator of fracture severity.
