Improved Insulin Sensitivity during Pioglitazone Treatment Is Associated with Changes in IGF-I and Cortisol Secretion in Type 2 Diabetes and Impaired Glucose Tolerance

Interstitial measurements in adipose tissue during OGTT in 10 subjects with type 2 diabetes (T2D) and 10 subjects with impaired glucose tolerance (IGT) at baseline (week 0) and after 12 weeks of pioglitazone treatment (mean ± SEM).
