Availability of data and materials
Deidentified data that support the findings of this study are available on reasonable request. Investigators who propose to use the data have to provide a methodologically sound proposal directed to the corresponding author. Signing a data use/sharing agreement will be necessary, and data security regulations both in Germany and in the country of the investigator who proposes to use the data must be complied with. Due to the data being closely connected with the participating departments, it might not be possible to sufficiently anonymize all persons in all documents within this data set. Thus, some documents might have to be excluded from sharing. Preparing the data set for use by other investigators requires substantial work and is thus linked to available or provided resources. The data sets used in this study are in German language.
