Recruitment details

Only 3 control (normal glucose tolerance) subjects were enrolled to obtain results in normal subjects for the hyperglycemic clamp (without GLP-1 or arginine). No samples were run, and, therefore, there are no data for the control subjects. No subjects with impaired glucose tolerance (IGT) were recruited or enrolled in the study.
