Summary
The purpose of this study is to determine predictors of response to pioglitazone, an anti-diabetic medication. The investigators know from randomized clinical trials that some 30% of patients do not respond to this type of medication. There is presently no way to identify this group of patients leading to unnecessary drug exposure and medication costs.
