What is the process used to revise the recommendations?
The recommendations were revised in a multistep process during a face-to-face meeting (New Orleans, LA, USA, January 2019) and by e-mail communication. The final draft was sent for external public review, and reviewers provided open-ended responses. Based on the external stakeholder feedback, the draft was further revised by Work Group Co-Chairs and members. All Work Group members provided feedback on initial and final drafts of the recommendation statement and guideline text and approved the final version of the guideline.
