Metabolic parameters in the normoinsulinemic women with PCOS (14 patients) before and after NAC treatment. Data are expressed as mean ± SD. A, AUC of insulin expressed as μIU/mL × 240 minutes. B, AUC of C-peptide expressed as ng/mL × 240 minutes. C, Total body glucose utilization (M) expressed as mg/kg/min. ∗P<.05 Before (pre) vs. after (post) NAC treatment.
