| MAP, mm Hg | 0.03 (0.01, 0.04) | 0.32 (0.13, 0.51) | |
| Total cholesterol, mg/dL | 0.08 (0.03, 0.13) | ||

Multiple linear regression with β coefficient and confidence intervals for β. All covariates were allowed to enter the model except height but not heart rate for AIx-75. Only significant covariates are listed above, p < 0.05. Models were adjusted for clinic site and time difference between visits. Alx-75, augmentation index; BMI, body mass index; BrachD, brachial distensibility; MAP, mean arterial pressure; PWV, pulse wave velocity.
