Ethics approval and consent to participate
The trial was conducted following the protocol, the Helsinki Declaration in its latest form, good clinical practice guidelines, and followed the rules for informed consent. GPs or practice staff contacted potentially eligible patients and obtained written informed consent. Danish law required no ethical approval for this study because it constituted a quality improvement project decided by the National Committee on Health Research Ethics in Denmark. The waiver of ethical approval was approved by the Center of Regional Development, the Capital Region of Denmark (cf. journal no. 20038096).All participants were anonymized, identifiers altered, and data derived from patients’ medical journals were encrypted. Data were stored and processed per the requirements of European General Data Protection Regulation (EU GDPR).
