Basal and postprandial plasma glucose (A) and insulin (B) concentrations and insulin secretion (C) and insulin clearance (D) rates in women with obesity and NFG and NGT, who were either insulin sensitive (Ob-NFG-NGT IS, n = 15) or insulin resistant (Ob-NFG-NGT IR, n = 15), defined as whole-body insulin sensitivity values above and below the median value for the entire group. Relationships between plasma glucose concentration and the ISR (E), plasma glucose concentration and plasma insulin concentration (F), the ISR and plasma insulin concentration (G), and plasma insulin concentration and the ICR (H) before and during the entire 180-minute postprandial period in the same participants. NFG values: plasma glucose at 0 minutes <100 mg/dL; NGT values: plasma glucose at 120 minutes <140 mg/dL. Data are expressed as the mean ± SEM or the median (quartiles).
