Linear regression models for second stage systolic BP and second stage diastolic BP were adjusted for risk factors listed in Table 2. Each set of vascular function variables (in bold) was evaluated in a separate model that did not include other vascular function variables. Results are presented as estimated regression coefficients (β) per 1 SD increment in the independent variables ± standard error (SE). (See Table 1 for SD of variables)
