Common use of Participant Recruitment Clause in Contracts

Participant Recruitment. United States based clinicians (including physicians, advanced practice providers, and other health care providers) who currently care for neurofibromatosis patients were eligible to participate in the survey. Potentially eligible participants were identified using registration lists for the 2016-2018 Children’s Tumor Foundation NF conferences, the largest NF-specific research conference in the U.S. Registration lists did not reliably differentiate whether conference attendees were clinicians or non- clinicians nor their country of residence, so all potentially eligible participants (n=358) were included in the recruitment process and we relied on screening questions at the start of the survey to filter out non- clinicians and those residing outside the U.S. The chair of the Children’s Tumor Foundation Clinical Care Advisory Board emailed survey invitations in September 2019, with a follow-up reminder email two weeks later. Participation in the survey was voluntary and anonymous. The study was deemed exempt by the Mass General Xxxxxxx Institutional Review Board.
