False-positive and false-negative classification of carotid stenosis derived from the simulation
| % Stenosis | True + Fraction | True − Fraction |
|---|---|---|
| 50 | 0.96 | 0.96 |
| 60 | 0.92 | 0.97 |
| 70 | 0.92 | 0.98 |
For all entries, 95% CI is approximately ±0.01.
Simulation used SD of 0.08 for selected cutpoints of clinical interest expressed as true-positive and true-negative fractions.
