Table 1. Blood flow waveform morphology by sex. Data are reported as median (interquartile range) over the 13 male and 17 female subjects at rest. Bold p-values denote significance assessed at the 0.05 level with a two-sided Wilcoxon rank sum test. (Abbreviations: EDF = end diastolic flow, MF = mean flow, PSF = peak systolic flow, AMP = pulse amplitude, AUC = pulse area under the curve, PI = pulsatility index, RI = resistivity index).
| Parameter | Males (n = 13) | Females (n = 17) | p-value |
|---|---|---|---|
| EDF (1e-9 cm2/s) | 4.41 (4.13, 5.51) | 7.78 (5.11, 11.26) | 0 . 012 |
| MF (1e-9 cm2/s) | 6.46 (5.16, 8.77) | 10.82 (8.27, 15.78) | 0.004 |
| PSF (1e-9 cm2/s) | 13.14 (10.91, 19.13) | 18.96 (13.86, 27.17) | 0.036 |
| AMP (1e-9 cm2/s) | 8.69 (6.11, 12.44) | 10.06 (8.47, 14.45) | 0.241 |
| AUC (1e-9 cm2/s) | 2.13 (1.59, 3.30) | 3.63 (3.27, 4.72) | 0.009 |
| PI (unitless) | 1.19 (1.02, 1.63) | 1.02 (0.82, 1.13) | 0.045 |
| RI (unitless) | 0.61 (0.57, 0.71) | 0.57 (0.51, 0.63) | 0.586 |
