Ethics approval and consent to participate
: The 1988 study was approved by the Danish Institutional Review Board. Subsequently, Danish Law specified that questionnaire studies did not require ethical approval [], so the 2001 and 2012 surveys did not require and could not obtain renewed approval. The questionnaires were accompanied by information regarding the participation being voluntary and having no impact on treatment. For children, parents filled out the questionnaire together with the participant or on behalf of the participant. Informed consent was given by returning a completed version of the questionnaire to the Danish Hemophilia Society, thus written consent was not applicable. For children, informed consent was provided by parents when participating. The Danish National Committee on Health Research Ethics approve consent in this form.
: Not applicable.
