All Guideline Writing Committee (GWC) members and reviewers are required to disclose current industry rela- tionships or personal interests from 12 months before initiation of the writing effort. Management of RWI involves selecting a balanced GWC and assuring that the chair and a majority of committee members have no relevant RWI (Appendixes 1 and 2). Members are restricted with regard to writing or voting on sections to which their RWI apply. For transparency, members comprehensive disclosure information is available. Comprehensive disclosure information for the Task Force is also available online. The Task Force strives to avoid bias by selecting experts from a broad array of backgrounds representing different geographic regions, sexes, ethnicities, intellectual perspectives/ biases, and scopes of clinical practice, and by inviting organizations and professional societies with related interests and expertise to participate as partners or col- laborators.
