Engberg S, Vistisen D, Lau C, Glümer C, Jørgensen T, Pedersen O, Borch-Johnsen K. Progression to impaired glucose regulation and diabetes in the population-based Inter99 study. Diabetes Care 2009;32:606–611

In the RESEARCH DESIGN AND METHODS subsection “Statistical analysis” in the print version of the article listed above, the recitation of “Wilcoxon signed-rank test” is incorrect and should be “Wilcoxon rank-sum test.” The authors used the Wilcoxon rank-sum test, and the results reported are correct.

The sentences in the RESEARCH DESIGN AND METHODS subsection “Statistical analysis,” second paragraph (pp. 607–608), should read “For individuals progressing to a relevant outcome, the date of exit was set at the midpoint between the first examination where the outcome was identified and the previous examination. This was to account for the fact that progressors will have converted at an unknown time somewhere between these examinations.” The calculations were correctly done; that is, the results reported are correct. The online version reflects these changes.
