Declarations
:
: All parts of the study were approved by the Regional committee for medical and health research ethics (2010/2014 REK Sør-Øst D), in accordance with the Declaration of Helsinki. Patients were enrolled at admission. Written informed consent to participate was obtained as soon as practically possible. A temporary written consent from the closest relative was obtained when patients were unable to consent. All material was destroyed if patients or relatives did not consent. The Regional committee for medical and health research ethics approved the use of biological material from patients who died before consent could be obtained, and the use of written information with the possibility for withdrawal for patients who were transferred to other hospitals or discharged before consent could be obtained. All those patients were checked against the Norwegian national biological research reservation registry before final inclusion.
: Written informed consent for publication of non-identifiable data was obtained together with the consent to participate.
: The authors declare that they have no competing interests.
