Values are reported as mean ± SD or number (percentage) of subjects; all medical history based on both self-report and diagnosis in-hospital post stroke.
BMI indicates body mass index; ccPWV, carotid–cerebral pulse wave velocity; cIMT, carotid intima-media thickness; baPWV, brachium-ankle pulse wave velocity; CMSA, the segment atherosclerosis between common carotid artery and the ipsilateral middle cerebral artery; blood pressure.
