: We have received the following information in an official document from the Ethics Committee:<i>“In the case of research projects at the Dresden University of Technology, physicians are generally to be consulted according to § 15, para. 1 of the professional regulations of the Saxon State Medical Association if the project “[...] interferes with the psychological and/or physical integrity of a human being” “or uses body materials or data are used that can be attributed to a specific human being [...]“. If the research project is carried out by other scientists at the TU Dresden, ethical advice should be sought according to § 1 para. 3 no. 1, 2 of the statutes of the Ethics Committee at the TU Dresden if “experiments on and with humans [...]“ or “epidemiological research with personal data [...]“ are or will be carried out. Conversely, this means that there is neither an obligation nor a compelling recommendation to obtain professional ethical or/and legal advice from the ethics committee if only anonymous data are processed, which are neither personal, nor can be related to persons.”</i>We received this official statement from the ethics committee at the Dresden University of Technology, Fetscherstr. 74, 01307 Dresden (Chairman of the Ethics Committee: PD Dr. med. Hermann Theilen) Internet:ExternalRef removed.The above points under which ethical advice must be obtained at the TU-Dresden do not apply to our study, so an ethics statement (or ethical consultation) was not required. (We did not conduct experimental research on patients, did not interfere with the psychological and/or physical integrity of a human being, did not use bodily materials or data that could be attributed to a specific human being, did not conduct experiments on or with human beings, and did not conduct epidemiological research). This is also in accordance with the Declaration of Helsinki, as this is not a human experiment but an anonymous survey. We adhered to the Declaration of Helsinki. In addition, we provided information on data privacy and data collection at the beginning of the questionnaire (informed consent). The questionnaire could only be started after confirming that the consent form had been read. Participation in the study was only possible with informed consent.
