AIx = augmentation index, PWVao = aortic pulse wave velocity, IMTcca = intima media thickness in both left and right common carotid artery, IMTrad = intima media thickness in right radial artery, IM-GSM = intima media grayscale median in both left and right common carotid artery, SBP = systolic blood pressure.
