Sex (0 = men, 1 = women), history of diabetes (0 = No, 1 = Yes) and mRankin scale at discharge ≥2 (0 = No, 1 = Yes) were included as categorical variables. Reference category of vascular disease: normal ABI and CS <50%.
BMI: body mass index. ICA: internal carotid stenosis. IMT: intima-media thickness (by 0.1 units). PAD: peripheral artery disease. ABI: ankle brachial index.
