Randomized trial evaluates glucose monitoring accuracy in Chinese adults with diabetes, indicating clinical utility.

This research aims to assess the performance and safety of a 15-day real-time continuous glucose monitoring system in individuals with diabetes.
Conducted a multicenter clinical evaluation using four sensors per participant, placed on upper arm and abdomen.
Primary outcomes measured included mean absolute relative difference, 20/20% agreement rate, and Clarke and Consensus Error Grid proportions.
Used a factory-calibrated model for accuracy assessment.
MARD values were 8.44% for the upper arm and 8.91% for the abdomen.
20/20% agreement rates were 95.78% for the upper arm and 94.41% for the abdomen.
Clarke Error Grid results showed 99.53% and 99.96% for the upper arm, and 99.46% and 99.82% for the abdomen.

Zhang et al. (2026) studied this question.
