Ethics approval and consent to participate
: All patients gave written informed consent. Dutch law specifies that ethics approval is only needed when ‘participants are subject to procedures or are required to follow rules of behaviour’ (). As this was not the case, the approval of the local research ethics committee (REC AMC Amsterdam) was waived, as confirmed in writing.
: We obtained written informed consent of all patients to use their anonymized data for research articles, teaching and - if applicable – development and revision of guidelines.
: The authors declare that they have no competing interests.
