: In our analysis, the investigators did not have a direct access to data from individual patients. They solely had access to summary results provided by the Research Data Centre. Therefore, according to German law, ethics committee approval and informed consent were not required. All pooled results have been anonymized by DESTATIS. This means that any information that could be used to identify an individual patient or a single center was censored by DESTATIS to ensure privacy. In addition, the data are checked and censored by DESTATIS to prevent any conclusions being drawn about an individual center.
