Document development:
Group leaders sent drafts to either the diagnosis (B.R. Celli) or treatment (M. Decramer) co-chair, who collated and edited the contributions from the groups. The diagnosis and treatment drafts were then sent to the remaining co-chairs ( J.A. Wedzicha and K.C. Wilson), who collated and edited the drafts into a single document. The final draft was sent to all participants for review and feedback, including patient advocates and representatives. Multiple cycles of revision, review and feedback followed until all participants agreed on a version of the draft.
