Accuracy of a Seventh-Generation Continuous Glucose Monitoring System in Children and Adolescents With Type 1 Diabetes
Authors' conclusion
The G7 CGM placed on the arm or abdomen was accurate in children and adolescents with T1D.
Study context
- Population
- Children and adolescents with T1D: ages 7 to 17 years (YSI venous comparator) and ages 2 to 6 years (capillary fingerstick comparator)
- Participants
- 122 vs 118
- Comparison
- G7 continuous glucose monitoring (CGM) placed on the arm vs abdomen, vs venous (YSI) or capillary comparator glucose
- Armn = 122
- Abdomenn = 118
- Outcome
- Overall accuracy vs YSI, ages 7 to 17 (15 437 matched pairs)
- Follow-up
- 10.5 days of use
