Declarations
:
: All the procedures performed in this study were in accordance with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards.
: Not applicable.
: Not applicable.
: All the guideline authors and participants disclosed their potential conflicts of interest (COI) before starting work on the guideline using the AWMF’s “Disclosure of Conflicts of Interest” form (version date: May 23, 2018). The originals are kept on file by the guideline coordinator. The conflict of interest disclosure forms were jointly reviewed and evaluated by all the guideline development group members during the online conference on October 6, 2020. Horst Kares, Nikolaos Giannakopoulos, Markus Heise, Alexander Meyer, and Dagmar Norden had no conflict of interest and no competing interest. Olaf Bernhardt was found to have a low-level COI (with no consequences), and Joerg Schlieper was found to have a high-level conflict of interest regarding MAD type, design, and adjustability. Since his expertise was indispensable, it was decided to exclude him from the discussions and voting on the relevant topics and to merely grant him the opportunity to submit his comments and opinions in writing.
