Performance of three simultaneously used real-time continuous glucose monitoring (rtCGM) systems around a physically active weekend camp in adults with type 1 diabetes: A prospective lab and real‐world study
Authors' conclusion
Dexcom G7 and FreeStyle Libre 3 showed very high accuracy, which could not be found for the Simplera rtCGM system.
Study context
- Population
- Adults with T1D (9 females; age 50 ± 12 years; HbA1c 6.6 ± 0.5%); 3-day lab phase with three 90-min group exercise sessions, then 4-day home phase
- Participants
- 20 adults
- Comparison
- Dexcom G7 vs FreeStyle Libre 3 vs Simplera rtCGM accuracy against capillary blood glucose
- Outcome
- MedARD [IQR] of sensor glucose vs reference capillary blood glucose
Methodological detailslab and real-world phases, simultaneous wear of three rtCGM systems, Duplicate capillary glucose (Contour Next One) every 2 h, 8:00 AM–10:00 PM
