Models were adjusted to age, gender, diabetes parameters (years of diabetes, medication and HbA1c), blood lipids, CRP, blood pressure, eGFR and smoking status
aDistensibility was not adjusted to blood pressure; bPlaque volume association was estimated by ordinal regression for carotid plaque volume group
