Ethics approval and consent to participate
: This study was outside the scope of the Swiss Human Research Act (HRA, Swiss Federal Council 2014) because no personal data concerning human diseases and concerning the structure and function of the human body were collected. However, the study has been assessed according to the <i>Checklist for the ethical evaluation of empirical studies that don’t need mandatory authorization (CEBE</i>S); No. CEBES-2016-04. Identities of subjects were completely anonymous (‘blind survey’) and the study was of non-interventional nature. Collecting consent documentation in this case would hamper anonymity, which is why the need for informed consent was waived for this study. However, a cover letter provided information regarding purpose and aim of the study, handling of data, as well as funding bodies and contact information of the principal investigators. Completion of the survey posed minimal risks to the subjects.
