Diagnostic accuracy of exercise-ABI and PVR parameters using conventional cut-off value in patients with ABI above 0.91
| Sensitivity (%) | Specifcity (%) | Positive predictive value (%) | Negative predictive value (%) | |
|---|---|---|---|---|
| Ex-ABI | 96.2 | 73.5 | 43.9 | 98.9 |
| UT | 55.6 | 84.2 | 44.1 | 89.4 |
| %MAP | 33.3 | 94.2 | 56.3 | 86.3 |
| Combination of UT and %MAP | 66.7 | 81.7 | 45.0 | 91.6 |
ABI: ankle-brachial pressure index; Ex: exercise; UT: upstroke time; %MAP: % mean artery pressure; PVR: pulse volume recoding
