Prep to Research


Process for Requesting Data

** Now that the CRN is an unfunded consortium, site participation in data requests is voluntary and dependent upon programmer and investigator availability. **


The Prep-to-Research (PTR) Form should be reviewed, completed, and submitted by any investigator who wishes to obtain summary counts to help with a grant application. Please note that these data are provided only for preparatory to research purposes and should not be used without explicit permission from sites. They may contain proprietary information, therefore permission is needed from each contributing site to use that site's numbers for any purpose including in a grant proposal, poster, or publication.

Reference Materials

If this is your first time submitting a Prep-to-Research Form with the CRN, please review the Investigator Guide (PDF, 272 KB) before proceeding. The purpose of the Investigator Guide is to serve as an introduction for scientific investigators who wish to obtain and analyze CRN data.

Once you have reviewed the guide, you may download (use Adobe to view this file) and complete the Preparatory-to-Research Form (PDF, 155KB).

Summary of the Process:

  • Requestor attaches the completed PTR Form in an email to:
  • The CRN will review the request with respect to feasibility, priority, effort, and consistency with CRN objectives.
  • Depending on the nature of the request submitted, the CRN may require that investigators not affiliated with the CRN identify a CRN investigator who is interested in collaborating on the project before completing the data request.
  • CRN programmer works with the requestor to clarify request, if necessary, and share results when complete.

While data are collected and maintained independently by each CRN Site, a system of data standards and automated processes known as the Virtual Data Warehouse (VDW) has been established to facilitate consistent data analysis across the network.
