In the commentary listed above, which appeared in the April 2014 issue of Diabetes, one of the authors did not disclose a financial conflict of interest. Dr. Josephine M. Egan is listed as an inventor on patents (US 7576050 and US 7056734) covering molecules described in the article. The reviewers and the editors were unaware of this interest at the time the manuscript was reviewed.

The online version reflects this change.
