Clinical Scores for History Only, and History + Dipstick: Sum Scores and Predicted Probabilities per Risk Category
| Risk Category | History Only | History+Dipstick | ||
|---|---|---|---|---|
| Score | Predicted Probability (95% CI) | Score | Predicted Probability (95% CI) | |
| <30% | ≤3 | 16 (7–34) | ≤12 | 15 (7–31) |
| 30%–70% | 4–8 | 56 (44–68) | 14–17 | 61 (41–77) |
| >70% | ≥11 | 79 (69–86) | ≥19 | 91 (76–96) |
Notes: For example, for history only, patients with a sum score of ≥3 have a predicted probability of 16% and are therefore classified into the lowest risk category (<30%).
