Data Request Number: 2018-3321 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):

The aims state that “Part of data will be used for model development, remaining part will be used for external validation.”
However, the methods imply that this validation is uncertain:  Some of the data may be reserved to perform an external validation of the mode.
The investigators should reconcile these statements and clarify their validation plan. 

Recommendation for this data request: Not Approve

just the minor clarification as above.
