| RI | 0.62 ± 0.07 | 0.72 ± 0.06 | <.001 | 0.86 |
| PSV | 93 ± 21 | 76 ± 15 | .007 | 1.2 |
| EDV | 35 ± 12 | 22 ± 6 | <.001 | 1.7 |
Note:—EDV indicates end diastolic velocity (cm/s); PSV, peak systolic velocity (cm/s); RI, resistance index.
↵a Ratio is the data collected from patients with DAVFs versus those of control subjects.
