Ethics approval and consent to participate
: All participants gave oral consent and the protocol was reviewed and declared not mandatory for submission by the Regional Committee for Medical and Health Research Ethics in Norway (2016/1505/REK Nord).The Regional Committee for Medical and Health Research Ethics in Norway reviewed the study protocol and declared it not mandatory for submission due to the ethically benign nature of the study. Even though the ethics committee did not need to approve the study, all participants were required to provide consent to participate in the study. Therefore, study participation was synonymous with documented consent. None of the authors had access to any personal or potentially identifying participant information. For practical purposes, and since written consent was not required, every participant provided oral consent.
