Declarations
:
: Strictly anonymous aggregated data such as the German national hospital statistics are exempt from ethical approval [CitationRef removed]. As such, no regulatory body may be able to grant ethical approval for something that is approved by the law itself. The owner of the data—the Statistisches Bundesamt (German federal statistics office)—licensed the data to the authors and did thereby authorise them to use and analyse the strictly anonymous data.
: Not applicable.
: The authors declare that they have no competing interests.
