337Technical Information
difference (%) from the SMBG values was calculated. The percentages of total readings within 15 mg/
dL or 15%, 20 mg/dL or 20%, 30 mg/dL or 30%, 40 mg/dL or 40% or greater than 40 mg/dL or 40%
were then calculated.
For example, if the system reads 100 mg/dL, it is between 81-180 mg/dL range and you can expect
the system readings to be within 20% of the SMBG values 85% of the time for the Software 505
Adult Study, as seen in Table 11-A.
Overall, the system in the Software 505 Adult Study reads, on average, 2.6% lower (Mean Percent
Difference) than SMBG values and 11.3% absolute different (Mean Absolute Percent Difference) than
the SMBG values. The Median Percent Difference shows that half of the time the system reads lower in
2.7% or less than the SMBG values and the Median Absolute Percent Difference shows that half of the
time the system reads about 8.6% or less different than SMBG values, as seen in Table 12-A.
Adverse Events
