aABI, Ankle-Brachial Index; BMI, body mass index; BP, blood pressure; CCA, common carotid artery; CV, cardiovascular; CSA, cross-sectional surface area; DBP, diastolic blood pressure, DM, diabetes mellitus; L, left; R, right; SBP, systolic blood pressure; SH, sustained hypertension; SN, sustained normotension; WCH, white coat hypertension. bAdjusted for age, gender, BMI and smoking. cAdjusted for age, gender, BMI and smoking and for mean office BP. Data were analyzed by regression analysis, analysis of variance or analysis of covariance as appropriate. Data in the SN group are presented only for those patients who had high normal office BP and as a consequence were advised to measure out-of-office BP.
