Ethics approval and consent to participate
: The study has been approved by the ethics committee at Lovisenberg Diaconal Hospital, Norway. The participants gave verbal consent to participate in the study. The reason for choosing verbal consent rather than written consent was because it was done in a clinical setting in the outpatient clinic at Lovisenberg Diaconal Hospital before written consent was introduced as standard in the hospital’s clinical studies. The verbal consent was approved by the ethics committee at Lovisenberg Diaconal Hospital, Norway on December 3rd 2014.
