  • Data are means ± SEM. Insulin was measured by immunoradiometric assay. Mean HOMA-IR values were calculated in 41 subjects using the formula [glucose (mmol/L) × insulin (mU/L)/22.5] (http://www.dtu.ox.ac.uk), excluding insulin- and/or sulfamid-treated subjects. Mann-Whitney U or Fisher exact tests were performed to compare nondiabetic and diabetic subjects.
