Improved glycemic control and lifestyle behaviors with Dexcom continuous glucose monitoring: one-year real-world outcomes from a global registry of people with non-insulin-treated type 2 diabetes in primary care
Authors' conclusion
In real-world primary care, Dexcom G7 CGM use in NIT T2D was associated with improved glycemia, weight, diabetes distress, diet, and lifestyle behaviors, supporting CGM adoption beyond insulin-treated populations.
