Performance Assessment of Three Continuous Glucose Monitoring Systems in Adults With Type 1 Diabetes
Authors' conclusion
The results of FBS were encouraging enough to conduct further performance and usability evaluations in a low- and middle-income country. The results of FL2 mainly agreed with existing studies, whereas ADX showed substantial deviations from previously reported results.
Study context
- Population
- Adults with T1D30 adults enrolled
- Comparison
- FiberSense vs FreeStyle Libre 2 vs GlucoRx AiDEX
- FiberSense system (FBS)n = 31 sensors
- FL2n = 70 sensors
- AiDEX (ADX)n = 78 sensors
- Outcome
- Accuracy vs comparator: mean absolute relative difference (MARD) and relative bias
- Follow-up
- 28-day study period
Methodological detailsmainly home-based, three in-clinic sessions, capillary blood glucose comparator, Study mainly at home with three in-clinic sessions over 28 days
- Mainly home-based
- Three in-clinic sessions
- Capillary blood glucose comparator
- Study mainly at home with three in-clinic sessions over 28 days
