^a; ^b. Continuous data were described as a mean ± SD and median (interquartile range). Categorical data were described as numbers (%). The chi-square test, independent sample t-test, and Mann–Whitney U test were used where appropriate. NFG = normal fasting glucose; IFG = impaired fasting glucose; BP = blood pressure; SBP = systolic blood pressure; DBP = diastolic blood pressure; PP = pulse pressure; MAP = mean arterial pressure; IAD = interarm difference; ILD = interleg difference; ABI = ankle-brachial index.
