Association Between Real-Time Continuous Glucose Monitoring Sensor Active Time and Glycemic Metrics in Patients With Diabetes: A Real-World Setting Analysis
Authors' conclusion
In real-world settings, higher CGM use was associated with better glycemic outcomes, including lower GRI, lower average blood glucose, lower GMI, lower TAR, lower TBR, and higher TIR. Future studies should examine factors influencing sensor use to inform strategies that promote effective CGM adoption.
