Statins: 0 = none, 1 = simvastatin 20 mg, 2 = simvastatin 40 mg, 3 = atorvastatin 20 mg, 4 = atorvastatin 40 mg; hyperlipidemia: 0 = cholesterol and triglycerides within normal range for age, 3 = requires dietary and drug control; hypertension: 0 = none, 1 = controlled with single drug, 2 = controlled with 2 drugs, 3 = requires more than 2 drugs or uncontrolled; smoking: 0 = none, or none for last 10 years, 1 = currently none, but smoked in last 10 years, 2 = current (includes abstinence <1 year).

R, Right side carotid stenosis; L, left side carotid stenosis; A. fugax, amaurosis fugax; TIA, transient ischemic attack; CVA, cerebrovascular accident; absent specifications represent asymptomatic patients.

* Degree of stenosis: carotid artery stenosis determined by duplex flow analysis.

^† Ratio FDGmax: highest FDG uptake corrected for background FDG uptake.

^‡ CD68: CD68 positive cells (macrophages) were semi-quantitatively scored; the average score is presented.
