Sensitivity and specificity of resting blood pressure measurements
| Sensitivity (%) | Specificity (%) | Positive predictive value (%) | Negative predictive value (%) | |
|---|---|---|---|---|
| Resting systolic pressure >140 mm Hg | 50 | 75 | 25 | 90 |
| Resting arm–leg gradient >10 mm Hg | 50 | 86 | 38 | 91 |
| Systolic pressure >140 and arm–leg gradient >10 mm Hg | 17 | 89 | 20 | 86 |
