Background characteristics of sample. Data are given as mean (SD) unless otherwise indicated. SBP indicates systolic blood pressure; DBP indicates diastolic blood pressure; FSRP = Framingham Stroke Risk Profile; IMT = intima medial thickness; mm Hg indicates millimeters of mercury; KGS indicates kilograms.
