In the print version of the article cited above, the affiliation for Eva Aguilera, Enric Serra, Núria Alonso, Silvia Pellitero, Jordi Lluίs Reverter, Isabel Salinas, Berta Soldevila, Dίdac Mauricio, and Manel Puig-Domingo is incorrect. The correct affiliation is as follows: Endocrinology and Nutrition Unit, Department of Medicine, Institute of Research and Hospital Universitari Germans Trias i Pujol, Universitat Autònoma de Barcelona, Badalona, Spain. In addition, the name of the second author should be Enric Serra-Planas, not Enric Serra.

The online version reflects these changes.
