The plot graph below is a representative example of continuous sensor tracing vs. reference blood glucose
reading, where sensor showed poor performance. The open circles (o) on the graph represent the meter
calibration readings. The closed circles (•) represent the reference blood glucose readings, and the solid
line (—) represents the sensor glucose value.

Performance results in children and adolescents
The performance of the Guardian RT in Children and Adolescents was evaluated in a clinical study.

Guardian RT results were compared to capillary blood glucose measured by a LifeScan OneTouch

Meter. Sixty subjects with Type I diabetes participated in a three-site out-patient study. Subjects ranged
in age from 7 to 17 years old. Each subject wore a Guardian RT system, which records a sensor glucose
value every five minutes. Subjects were instructed to perform at least seven blood glucose meter
measurements each day.
Accuracy of Guardian RT readings
In this study, each blood glucose meter measurement was paired with the corresponding Guardian RT
reading (taken every 5 minutes). Pairing was done by selecting the Guardian RT value closest in time to
the blood glucose meter result. Agreement was analyzed by comparing paired glucose measurements.
