Erratum to: Int Arch Occup Environ Health (2009) 82:417–426 DOI 10.1007/s00420-008-0339-8

We have discovered three errors in Table 1: (i) the numbers in the first two lines have been interchanged; (ii) in the last line but two the text is wrong as self-employed are not included in sample (the stated number of excluded participants is correct, though); and (iii) the figure for No response should be changed to N = 3,049 and the corresponding percentage to 38.9. The corrections do not have any influence on our conclusions.

Table 1 Dropouts and non respondents

In addition to the original authors, we would also like to include Helene Feveile in the list of authors of the erratum, so that the list of authors is: Adriana Ortega, Annie Høgh, Jan Hyld Pejtersen, Helene Feveile and Ole Olsen.
