Another estimate used to show the accuracy of the System is the

absolute percent difference. The absolute percent difference tells

you the percent difference or “distance” between the System and YSI

values, but does not tell you whether the System is reading, on average,

higher or lower than the YSI laboratory standard. The mean absolute

percent difference is the average “distance” (regardless if positive or

negative) between System readings and YSI values.

Accuracy measures in differences for both the Original and Software

505 Studies are based on 9152 and 2263 paired glucose results,

respectively; the data are summarized in Table 4. Table 4 is categorized

within CGM glucose ranges.

Original Study (SW10050): Overall, on average, the System reads

2.9% different (Mean Percent Difference) than the reference and 13.3%

absolute different (Mean Absolute Difference) than the reference values.

The Median Percent Difference shows that half of the time the System

reads 1.7% or less than the YSI blood glucose values and the Median

Absolute Percent Difference shows that half of the time the System

reads about 9.8% or less than the YSI blood glucose values.

Software 505 Study (SW10505): Overall, on average, the System

reads 2.5% different (Mean Percent Difference) than the reference and

9.0% absolute different (Mean Absolute Difference) than the reference

values. The Median Percent Difference shows that half of the time the

System reads 2.4% or less than the YSI blood glucose values and the

Median Absolute Percent Difference shows that half of the time the

System reads about 7.0% or less than the YSI blood glucose values.
