Declarations
:
: The Regional Committee for Medical and Health Research Ethics of Northern Norway approved the survey protocol (Ref 2010/1056–4). Informed consent from individual patients was not considered necessary by this committee, considering that data were to be collected anonymously for all consecutive adult patients and that no patients were to be contacted. Only the individual GP knew the identity of each of his/her own patients, and none of the authors had access to this. Ethics approval was thereafter given also in the other five participating countries.All methods were carried out in accordance with relevant guidelines and regulations, We have gone through a Strobe checklist for observational/cohort studies and a Stard checklist for diagnostic/prognostic studies.
: Not applicable.
: None of the authors declares any conflict of interest.
