Type 1 Diabetes Mellitus research study

What is the primary objective of this study?

The purpose of this study is to determine what the effects are of real-time continuous glucose monitoring on glycemia and quality of life in patients with type 1 diabetes mellitus and impaired hypoglycemia awareness.
