Ethics approval and consent to participate
: Oral informed consent was obtained from all interview participants and other research ethics requirements, such as data anonymity, were observed diligently. We did not obtain institutional ethics approval as the study is a socio-empirical work and not biomedical research and was carried out mainly by social scientists. The approval of a research ethics committee in Germany is legally required only for studies which fall under the Drug Law or the Medicinal Products Law.
