Data Request Number: 2018-3476 Is the scientific purpose of the research proposal clearly described?: Yes Will request create or materially enhance generalizable scientific and/or medical knowledge to inform science and public health?: Yes Can the proposed research be reasonably addressed using the requested data?: Yes, or it’s highly likely Please use this space to provide any comments, feedback or concerns (optional):

Investigators propose to combine data obtained from other data sharing platforms (e.g. CSDR, Vivli) – this will likely require discussions with the sharing companies and decisions about which secure platform to use. Investigators are also requesting endoscopic scores and histologic results, which I do not expect to be available.

Recommendation for this data request: Approve
