The article entitled “Regional Differences in the Prevalence of Cardiovascular Disease—Results from the German Health Update (GEDA) from 2009–2012” by Dornquast et al in issue 42 of Deutsches Ärzteblatt (21 October 2016) contains two numerical errors. In the methods section, the authors reported the response rates of the included GEDA studies. The values of 23.9% and 34.5% for GEDA 2012 and 2009 are incorrect. The correct proportions are 22.1% (GEDA 2012) and 29.1% (GEDA 2009). MWR
