Peripheral and central blood pressure values and arterial stiffness according to blood pressure and tHcy level.

SBP: systolic blood pressure; DBP: diastolic blood pressure; PP: pulse pressure; MAP: mean arterial blood pressure; cf-PWV: carotid-femoral pulse wave velocity; central AIx P75: central augmentation index corrected for a heart rate of 75 bpm. Low tHcy was defined as tHcy *After adjustment for age, gender, heart rate, MAP, blood glucose, and current smoking; **after adjustment for age, gender, body mass index, MAP, blood glucose, and current smoking.Crude P for difference between strata (High tHcy versus Low tHcy). Corrected P value was obtained by Bonferroni’s correction for multiple testing. In a one-way ANOVA involving 4 group means, there are 4 pairwise comparisons. Thus, Corrected P value = Crude P Value*4.
