^a. values were calculated using Pearson’s correlation coefficient (r). FBG = fasting blood glucose; BP = blood pressure; ABI = ankle-brachial index; SBP = systolic blood pressure; DBP = diastolic blood pressure; PP = pulse pressure; MAP = mean arterial pressure; IAD = interarm difference; ILD = interleg difference.
