Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE)
What is GRADE?
GRADE is a long-term study of different treatments for type 2 diabetes funded by the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health (NIH). Type 2 diabetes is an epidemic that threatens to become the century's major public health problem and poses enormous human and economic challenges worldwide. Most people with diabetes eventually need 2 medications to control blood glucose levels. A major challenge is to determine which of the many possible drugs is the best choice among people already treated with metformin, the most commonly used diabetes drug. GRADE will determine which combination of two medications is best for glycemic control, has the fewest side effects, and is the most beneficial for overall health.
