DCCT and EDIC: The Diabetes Control and Complications Trial and Follow-up Study

The Diabetes Control and Complications Trial (DCCT) was a major clinical study con­ ducted from 1983 to 1993 and funded by the National Institute of Diabetes and Digestive and Kidney Diseases. The study showed that keeping blood glucose levels as close to normal as possible slows the onset and pro­ gression of the eye, kidney, and nerve damage caused by diabetes. In fact, it demonstrated that any sustained lowering of blood glucose, also called blood sugar, helps, even if the per­ son has a history of poor control.
