Data and Sample Requests

There are two ways to access data and samples from the DCCT/EDIC Study. One is via the NIDDK Repositories, which have data and samples available for distribution through 2011. The second is to apply to collaborate with the EDIC Study.

 

Accessing data and samples via the NIDDK Repository

 

Collaborating with the EDIC Study

All collaborators should agree to the EDIC Publications and Presentations Policy and the Ancillary Studies Policies that are contained in Chapter 8 of the EDIC Protocol.

Feasibility Statement*

Prospective investigators should be aware that there is a finite quantity of specimens in both the EDIC Central Biochemistry Laboratory (CBL) and the NIDDK Repository, and some samples may have been depleted or may have very low volumes. Therefore, a sample of subjects with available specimens may be a biased representation of the DCCT/EDIC cohort. Availiability of adequate numbers of subjects with available specimens will be a criteria on which the Research Review Committee (RRC) will base their evaluations of a new proposal.

Characteristics and Complications for Those Who Agreed or Refused to Send Samples to the Repository

 

*Potential collaborators may require information to allow them to best evaluate the possibilities for collaborations with EDIC or to plan the design (e.g. sample size) for a study. Investigators who would like to obtain specific numbers of cases of specific outcomes that have occurred during EDIC should contact Ms. Patricia A. Cleary at cleary@bsc.gwu.edu.
