Participant Flow

Participants enrolled at 125 investigative sites in Argentina, Australia, Brazil, Chile, Dominican Republic, Germany, Guatemala, India, Mexico, New Zealand, The Netherlands, Poland, South Africa, Spain, and the United States from 04 April 2006 to 20 June 2007.

Participants with a historical diagnosis of type 2 diabetes mellitus who were inadequately controlled while receiving a stable dose of glyburide monotherapy were enrolled in one of 3, once-daily (QD) treatment groups.
