Data Request Number: 2017-1846 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?: Unsure, would defer to Data Holder Due Diligence Assessment Please use this space to provide any comments, feedback or concerns (optional):

I very much doubt that the datasets requested will contain useful and representative data on adverse effects of withdrawal. Adherence rates are typically poor in  populations with psychotic illness and when participants are lost to follow-up they are generally not traced or traceable.
Further clarification from data holder and/or applicant is needed.

Recommendation for this data request: Not Approve
