: Ethical approval for this study was obtained from the ethics committee of the University of Ulm (approval reference: 102/23, approval date: 05.04.2023) and University of Tübingen (approval reference: 537/2019BO2, approval date: 30.07.2019). The study is based on a retrospective analysis of anonymized, routinely collected clinical data. As such, the data were already available in institutional records prior to the study initiation, and no interventions or additional data collection outside routine care were performed. Both ethics committees explicitly waived the requirement for informed consent and approved the use of historical data without restrictions on the date range of the data included. Thus, neither additional IRB waivers are required nor is exclusion of data collected prior to the approval dates necessary. No data beyond the cut-off date of September 2024 were included in the analysis. All data were fully collected and finalized prior to manuscript submission. This research was conducted in full accordance with the ethical standards of the institutional research committee as well as with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. For this non-interventional observational retrospective study, all data were also anonymized and de-identified prior to analysis. Full compliance with data protection and safeguarding of data was ensured and no information which could identify the patients was collected. Reporting was based on the recommendations of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) initiative [].
