Impact of Body Composition on the Accuracy of a Medtronic Guardian Continuous Glucose Monitoring System
Authors' conclusion
Body composition does not have a meaningful impact on the accuracy of CGM systems.
Study context
- Population
- Participants >7 years using an investigational Medtronic Guardian sensor 3; mean BMI Z score 0.48 (<18 years) and BMI 26.7 kg/m² (≥18 years)
- Participants
- 112 participants
- Outcome
- Absolute relative difference between sensor and blood glucose readings, by body composition (BMI, midarm circumference, % fat, impedance)
- Follow-up
- 7 days
Main finding
As reported in the abstract
Association of body composition with continuous glucose monitoring (CGM) accuracy
- No statistically significant associations between measures of body composition and device accuracy
- Generalized estimating equations
Observational data: associations, not effects.
