Randomized trial evaluates accuracy of a new glucose monitoring system in adults with diabetes, indicating reliable performance.

To assess the performance of the uCGM 100 continuous glucose monitoring system against venous plasma reference values.
Conducted a multicenter, prospective clinical trial in China with 60 adult participants.
Participants wore the CGM sensors for 15.5 days with three in-clinic visits for venous plasma glucose measurements.
Evaluated sensor accuracy using MARD and %20/20 agreement rate for matched data pairs.
MARD was 7.6% with a %20/20 agreement rate of 95.5% with reference values.
Agreement rate remained above 93% across sensor wear days and glucose ranges.
99.8% of participants provided positive feedback on usability.
