Clinical Studies on Efficacy of Continuous Glucose Monitoring

In the previous years, several studies have shown that the real-time (RT)-CGM systems are safe and effective in T1D, reducing the time spent in hypoglycemia and hyperglycemia, reducing overall diabetes-related complications and improving both glycemic control and patient quality of life. Even if it may seem intuitive that more glucose data should improve glucose control, it has been difficult to identify a causative relationship, even in pediatric studies, which did not show uniform benefits. The benefits of CGM have been primarily seen in those patients who use their devices for more than 70% of the time (≥ 5 days per week) [1–5].
