Data Request Number:
Is the scientific purpose of the research proposal clearly described?:
Will request create or materially enhance generalizable scientific and/or medical knowledge to inform science and public health?:
Can the proposed research be reasonably addressed using the requested data?:
Unsure, further clarification from requestor is needed
Please use this space to provide any comments, feedback or concerns (optional):
The proposal indicates “I am not analyzing participant-level data” but the analytic plan suggests that this is not the case. For instance: “Individual subject level data from the requested study will be screened…and “…. Kaplan-meier survival curves will be generated, within PS quintiles….”
Recommendation for this data request:
Are the outcomes (Oswestry Disability Index score, assessment for neurologic deficit, receipt of additional surgical intervention) all incorporated into the HEALOS database?
