Declarations
:
: The Ethics Committee of the Charité University Clinic Berlin approved this study (IRB no. EA4/111/18). The research was carried out in line with the principles of the Declaration of Helsinki. All study participants were provided with an information sheet in one of the nine languages available, which included information on the purpose and nature of the study, potential benefits and risks, and data handling, use and protection including anonymity of participation. They were given the option to ask questions, raise concerns, refuse to answer particular questions, refuse participation altogether, and/or file a complaint. Participants gave verbal consent to participate in the study; moreover, the returning of a filled-out questionnaire was regarded as an expression of consent. Due to the anonymity of the survey, it was not possible to withdraw from the study at a later stage. All received information were stored securely, with access reserved to the research team, to assure confidentiality. Feeding-back and discussing the study results with participants had been planned; however, this became impossible due to the Covid-19 pandemic and related restrictions.
