Declarations
:
: The study is a strictly retrospective data analysis. The study was reported in writing to the Ethics Committee of the North Rhine Medical Association Association (Ärztekammer Nordrhein) in June 2017. Due to the study type (retrospective data analysis), approval was given, but because of the regulations in use at that time, no ethics procedure was initiated. For the same reason, after consultation with North Rhine Medical, consent for participation was deemed unnecessary.
