Data are presented as mean±SD or number (percentage). ABI indicates ankle‐brachial index; AIx, augmentation index; baPWV, brachial to ankle pulse wave velocity; cfPWV, carotid to femoral pulse wave velocity; DBP, diastolic blood pressure; faPWV, femoral to ankle pulse wave velocity; hcPWV, heart to carotid pulse wave velocity; hfPWV, heart to femoral pulse wave velocity; PWV, pulse wave velocity; SBP, systolic blood pressure.
a
P<0.05 by t test (subtype II or III vs I).
b
P<0.05 by t test (subtype III vs II).
