Accuracy, safety, and usability of a real-time continuous glucose monitoring system in pediatric diabetes management.
Article in Journal of diabetes investigation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe purpose of the study was to evaluate the accuracy, safety, and usability of a real-time Continuous Glucose Monitoring (CGM) system compared with venous blood glucose (vBG) in children and adolescents.
methodsThe study enrolled 81 participants aged from 3 to 17 at three sites in China. Two sensors (GS1, SiBionics, Shenzhen) were inserted on the back of each upper arm for up to 14 days for each participant. A variety of analyses were conducted for evaluating accuracy by comparing the CGM readings and vBG values, including 20%/20 agreement rate, the mean absolute relative difference (MARD), the Clarke error grid, and consensus error grid analyses. Safety was measured by adverse event (AE) monitoring. AEs were documented, and the incidence rate was calculated. Usability was evaluated by self-reported questionnaires.
resultsData from 80 participants were analyzed. Our results demonstrated high accuracy of the real-time CGM system. The 20%/20 agreement rate across all glycemic ranges was 93.9%. The MARD value was 8.7%. The results of the Clarke and consensus error grid analyses in zone A + B were 99.6% and 100%, respectively. The average score of usability was 95.3 ± 7.6, reflecting high satisfaction. The CGM also showed high safety, given that only 3 device-related AEs in 2 participants were reported , and no serious adverse events (SAEs) were reported.
conclusionThe real-time CGM system demonstrated high accuracy, safety, and usability in the glycemic monitoring of children and adolescents.
