 Frequency of the metabolic syndrome criteria in patients with SLE and controls*

Patients with SLEControlsp Value
HDL, high-density lipoprotein; NCEP, National Cholesterol Education Program Adult Treatment Panel III; SLE, systemic lupus erythematosus; WHO, World Health Organization.
*p Values were calculated using Fisher’s exact test.
†Hypertension is defined as ⩾130/85 mm Hg or use of drugs for blood pressure in the NCEP criteria and ⩾140/90 mm Hg or use of drugs for blood pressure in the WHO criteria.
‡Insulin resistance defined by the presence of any of the following three criteria: a homeostasis model assessment index (fasting glucose (mmol/l)×fasting insulin (μU/ml)/22.5 in the top quartile of a population without diabetes (>2.114 in the Study of Inherited Risk of Coronary Atherosclerosis sample), impaired fasting glucose (⩾110 mg/dl) or diabetes.
