Values are expressed as mean ± standard error.

AIx, augmentation index; AP, augmentation pressure; bDBP, brachial diastolic blood pressure; bMAP, brachial mean arterial pressure; bPP, brachial pulse pressure; bSBP, brachial systolic blood pressure; cDBP, central diastolic blood pressure; cf‐PWV, carotid‐femoral pulse wave velocity; cPP, central pulse pressure; cSBP, central systolic blood pressure.

P: white vs black.

^a P: black vs nonblack.

^bAdjusted by central mean arterial pressure (cMAP), sex, and age.
