Birt and his affiliation should have been given as “Sandwell Primary Care Trust, Birmingham, UK.” The funding statement should also have read as follows: “This research project was co-funded by EU Commission, under the 7th Framework Programme (FP7/2007-2013) as part of the EUROURHIS 2 project (grant agreement no. 223711), Sandwell Primary Care Trust Public Health team and the project beneficiaries.” These errors have now been corrected online.
