ABI = ankle brachial index; BMI = body mass index; CAC = coronary artery calcification; CRAE = central retinal arteriolar equivalent; CRP = C-reactive protein; CRVE = central retinal venular equivalent; DM = diabetes mellitus; HbA1c = hemoglobin A1c HDL = high density lipoprotein cholesterol; Log = logarithm; MI = myocardial infarction; RP = retinopathy; SBP = systolic blood pressure.
Adjusted for age, gender, race, and follow up time.
Adjusted for variables in model a plus cardiovascular risk factors including total cholesterol, HDL-C, log of triglycerides, lipid-lowering medications, SBP, anti-hypertension medications, smoking status and cigarette pack-years.
Adjusted for variables in model B plus and BMI, log of CRP, Fibrinogen, log of HbA1C, log of creatinine, glucose, albuminuria, ABI, use of insulin or oral hypoglycemics and family history of MI.
Adjusted for variables in model C and CRAE and CRVE.
