Ethics approval and consent to participate
: The first page of the questionnaire explained the purpose of the research, the measures taken to protect respondents’ confidentiality and the voluntary nature of participation. Questionnaire respondents were asked to tick ‘agree’ at the start of the questionnaire to indicate that they consented to take part in the study and were willing to complete an anonymized questionnaire. Ethics approval was deemed unnecessary according to national regulations (law of 4 April 2014; ExternalRef removed), as participation was anonymous and no medical data were processed.
: Not applicable.
: The authors declare that they have no competing interests.
