: All documents were handed over to the responsible ethics committee. As this was a retrospective quality assurance study of standard procedures, with no experimental interventions, no specific consent was required from the patients. For the interventions during treatment, the patients were informed verbally and in writing, and written consent was obtained. The responsible ethics committee (Ethikkomssion Nordwest- und Zentralschweiz) has issued a declaration of no objection. The corresponding project number is EKNZ 2014 − 343.
