BMI: body mass index; SBP: systolic blood pressure; FPG: fasting plasma glucose; DBP: diastolic blood pressure; TC: total cholesterol; TG: triglycerides; HDLc: high-density lipoprotein cholesterol; LDLc: low-density lipoprotein cholesterol; CCA: common carotid artery, ICA: internal carotid artery; ECA: external carotid artery; VA:Vertebral artery.
*plaque composition: if all the plaques had the same composition, subject was classified into with this plaque composition, if had different composition, subject was classified into with polytype plaques.
