Table 3 Pulse wave velocity (PWV) and Doppler ankle-brachial index (ABI) correlations (N=259).
| PWV | Doppler ABI <0.9n (%) N=44 | Doppler ABI ≥0.9n (%) N=215 | Spearman’s correlation (p, r) |
|---|---|---|---|
| >uPWVt | 27 (61.4%) | 98 (45.6%) | 0.057, 0.12 |
| ≤uPWVt | 17 (38.6%) | 117 (54.4%) | |
| >iPWVt | 25 (56.8%) | 72 (33.5%) | |
| ≤iPWVt | 19 (43.2%) | 143 (66.5%) | |
| PWV – pulse wave velocity; uPWVt – universal fixed PWV >10 m/s; iPWVt – individualized PWV threshold calculated by the device; ABI – ankle-brachial index; r – Spearman’s rho correlation value. | |||
