Participant Flow

A total of 2,368 patients were enrolled at 49 clinical centers from United States, Canada, Brazil, Mexico, Czech Republic, and Austria between January 1, 2001 and March 31, 2005. Each of the 2368 patients was simultaneously assigned to initial revascularization or medical therapy and assigned to insulin providing or insulin sensitizing therapy.
