Ethics approval and consent to participate

: According to Danish legislation, qualitative studies are based on a written and informed consent and not on ethical approval from a national or public agency [–]. Permission for the collection, storage and processing of data was granted by the Danish Data Protection Agency (j.nr. 2015-41-3707). The obstetric unit approved the study and assisted the researchers in identifying potential interviewees from the intervention group of the RCT study. The women were then approached by phone and invited to participate in this qualitative, adjunct study as well. Only the interviewees and we knew who were finally included in this study. In accordance with national recommendations, the study purpose and publication strategy was clarified for the participants in writing and orally at recruitment and women were informed how their data would be protected, handled in strict confidentiality and reported, that participation was totally voluntary, and that they could withdraw their consent at any time [–].
