Compliance with ethical standards
:
: JC received honoraria for serving on the scientific advisory board of UCB Nordic and Eisai AB and for giving lectures for UCB Nordic and Eisai AB. JC also received funding for a trip from UCB Nordic. The other authors have no competing interests.
: All procedures performed in this study were in accordance with Danish ethical standards and with the Helsinki Declaration. The Danish Data Protection Agency has approved the study (reference number 1-16-02-691-14). The Ethics Committee of Central Denmark Region was contacted. The committee subsequently stated that the present study does not require approval. According to Danish law, questionnaire and register-based studies only need approval from the committee if the data include human biological material (§ 14) [CitationRef removed]. The correspondence with the ethical committee can be obtained from the authors on request. All data were stored and treated with confidentiality. Results from Statistic Denmark are only accessible for the researcher at an aggregated level, not at the individual patient level.

The patient was furthermore informed that the consent of participation could be withdrawn at any time.
