What this research studies

If you take part, researchers follow people who had type 1 diabetes and collect regular exams, lab tests, imaging, and questionnaires to track health over time. They use standardized tests and carefully review events like vision loss, kidney disease, nerve damage, and heart problems. The team also studies genetic and other biological markers to help explain why some people develop complications and others do not. This work continues long-term follow-up of an earlier group where early intensive glucose control showed lasting benefits.

Who could benefit from this research

Good fit: Adults with type 1 diabetes—particularly those who were part of the original DCCT or who can share long-term medical records and attend periodic follow-up visits—are the intended participants.

Not a fit: People who do not have type 1 diabetes (for example those with type 2 diabetes) or those unable to attend follow-up visits or provide medical history are unlikely to receive direct benefit from participating.

Why it matters

Potential benefit: This work could clarify how early blood sugar control prevents long-term complications and help shape better long-term care for people with type 1 diabetes.

How similar studies have performed: The original DCCT showed that early intensive glucose control substantially reduced eye, kidney, and nerve complications, and EDIC has already demonstrated lasting benefits, making this extended follow-up a continuation of prior successful work.
