Agreement between the matched pair was estimated by evaluating the difference between the Guardian
RT reading and the YSI measurement. The difference between them was calculated as a percentage of the
YSI (Mean Absolute Percent Difference). The bias was also calculated, and it is defined as the overall
difference between the Guardian RT glucose values and the YSI values. The paired glucose measurements
are summarized below.
Number of Paired Glucose Measurements 3941
Mean Absolute Percent Difference (± SD) 19.7 ± 18.4%
Bias -15.0 mg/dL (-0.8 mmol/L)
The accuracy of the Guardian RT was also evaluated by calculating the percentage of Guardian RT
readings within 20 percent and within 30 percent of the YSI reading (or within 20 mg/dL (1.1 mmol/L) in
the low glucose range). Results are shown below.

a. For the Low glucose range, 40-80 mg/dL (2.2-4.4 mmol/L), the value shown is the percent within
20 mg/dL (1.1 mmol/L).
