Ethics approval and consent to participate
: The responsible local ethics Committee at the Bavarian medical association waived the need for ethics approval and informed consent (registration number: 18-040; Bayerische Landesärztekammer, BLÄK). Thus, according to national regulations, written informed consent was not required. Participation in this questionnaire study was voluntary and anonymous; hence the authors assume the will to participate as a sign of consent.
: Not applicable.
