Sensitivity, specificity, accuracy, and odds ratio for different cutoff values of CI as well as for Nugent score and the presence of intracranial fat prolapse
| Parameter | Cutoff Value | Sensitivity/Specificity | Accuracy (95% conf. int.) | Odds Ratio (95% conf. int.) |
|---|---|---|---|---|
| Crowding index at 12 mm | 38.5% | 80.6%/81.4% | 80.0 (69.9–87.5) | 15.3 (4.9–49.3) |
| Crowding index at 18 mm | 57.5% | 91.7%/89.8% | 90.5 (0.82–0.95) | 97.2 (19.6–572.9) |
| Crowding index at 24 mm | 72.0% | 83.3%/81.4% | 82.1 (72.3–88.8) | 21.8 (6.5–77.2) |
| Fat prolapse | presence | 33.3%/81.4% | 0.63 (53.9–72.0) | 2.2 (0.8–6.3) |
| Subjective crowding score | ≥1 | 58.3%/84.7% | 74.7 (64.6–82.8) | 7.8 (2.7–23.3) |
