Impact of Body Composition and Anemia on Accuracy of a Real-Time Continuous Glucose Monitor in Diabetes Patients on Continuous Ambulatory Peritoneal Dialysis
Authors' conclusion
In summary, this real-time CGM demonstrated good accuracy in CAPD with minimal influence from body composition and anemia.
Study context
- Population
- Patients with diabetes on continuous ambulatory peritoneal dialysis (CAPD); age 64.7 ± 5.6 years (mean ± SD), 23 men, BMI 25.4 ± 3.9 kg/m², Hb 10.7 ± 1.3 g/dL941 paired readings
- Participants
- 30 patients
- Primary endpoint
- MARD between paired sensor and YSI 2300 STAT venous glucose readings
- Follow-up
- 8-h in-clinic session
Methodological details8-h in-clinic session with glucose challenge, Body composition evaluated using bioimpedance
- 8-h in-clinic session with glucose challenge
- Body composition evaluated using bioimpedance
Primary result
As reported in the abstract
Overall MARD, sensor vs YSI 2300 STAT venous glucose (n = 941 paired readings)
Overall mean absolute relative difference (MARD)
10.4%
95% CI 9.6–11.7
Further findings
Correlation of body composition with MARD
- No correlations between BMI, extracellular water, relative hydration index, and lean or fat mass with MARD
Correlation of Hb with MARD
- No correlation between MARD and Hb (r)
- 0.016, P > 0.05
