Correction to: npj Primary Care Respiratory Medicine (2014) 24, 14055; doi:10.1038/npjpcrm.2014.55; published online 28 August 2014

Since the online publication of the above article, we have received feedback from the co-author of one of the papers cited in the article (reference 4—Peters et al.) concerning the citing of their paper in relation to the content and format of Table 1. The authors of the above article fully acknowledge that confusion may have arisen because of the positioning of citation numbering at that point, and have expressed their sincere apologies to Peters et al. for this error.

The offending sentence has now been edited for clarity.

On page 1, paragraph 1, the following text:

‘The two others were related to the patient (socio-economic status (SES) and ethnicity) (Table 1).3 As the Dutch College of General Practitioners…’

Has been replaced by:

‘The two others were related to the patient (socio-economic status (SES) and ethnicity) (Table 1). The format of Table 1 is based on Peters et al.,4 the contents of Table 1 are based on Dirven et al.3 As the Dutch College of General Practitioners…’

The authors would like to apologise for this error. The error has been corrected in the PDF and HTML versions of the article.
