SBP indicates systolic blood pressure.

Presented data are for the extended model; regression coefficients were adjusted for age, education, gender, ethnicity, diabetes, pulse pressure, BMI, total cholesterol, smoking (Y/N), alcohol (Y/N). Note the same pattern of significant results with similar regression coefficients were obtined for the basic model, and thus are not shown.

^*Mean calculated from the 5 individual systolic BP measures taken in each position (sitting, recumbant, standing), and total mean calculated from all 15 individual systolic BP measures.

^†Variability calculated as the SD of the 5 individual systolic BP measures taken in each position (sitting, recumbant, standing), and overall variability calculated as the SD of all 15 individual systolic BP measures.
