: The study was conducted in accordance with the ethical principles of the Declaration of Helsinki [CitationRef removed], and national regulatory requirements, e.g., data protection regulations. The Regional Committee for Medical and Health Research Ethics in the South-East Health Region (REK 2014/2225) approved the study. As the professionals tried to call all new patients during the study period (not only those who later consented to be included in the dropout analysis), we specifically obtained ethical permission to do the no-show analysis on all eligible patients. All participants provided written informed consent before inclusion in the dropout study sample.
