| Peripheral SBP (mm Hg) | 133 ± 18 | 126 ± 15 | 0.011 |
| Peripheral DBP (mm Hg) | 81 ± 8 | 78 ± 7 | 0.014 |
| Central SBP (mm Hg) | 125 ± 17 | 118 ± 15 | 0.014 |
| Central DBP (mm Hg) | 82 ± 8 | 78 ± 8 | 0.019 |
| Mean pressure (mm Hg) | 100 ± 11 | 95 ± 10 | 0.010 |
| Heart rate (bpm) | 64 ± 11 | 61 ± 7 | 0.042 |
| AIx@75 (%) | 25 ± 9 | 22 ± 11 | 0.078 |
| cf-PWV (m/s) | 9.1 ± 2.2 | 8.2 ± 1.5 | 0.007a |
| C1 (mL/mm Hg × 100) | 12.8 ± 4.4 | 14.1 ± 5.0 | 0.119 |
| C2 (mL/mm Hg × 100) | 4.2 ± 3.6 | 6.0 ± 2.7 | 0.002 |
SBP: systolic blood pressure, DBP: diastolic blood pressure, AIx@75: augmentation index corrected for a heart rate of 75 beats per minute, cf-PWV: carotid to femoral pulse wave velocity, C1: large artery elasticity index, and C2: small artery elasticity index.
All variables are adjusted for body mass index.
aAdjusted for mean arterial pressure.
