* For YSI reference range ≤80 mg/dL, the differences in mg/dL are included instead of percent difference (%).
Note: SG Readings are within 40-400 mg/dL.
Percent agreement, by number of daily calibrations
In Tables E-2 through E-9, the agreement of the SG values to paired YSI values was
assessed by calculating the percentage of YSI values that were within 15%, 20%,
30%, 40%, and greater than 40% of the paired SG values. For readings less than or
equal to 80 mg/dL, the absolute difference in mg/dL between the SG and paired
YSI values was calculated.
Results are shown for defined SG ranges when calibrating every 12 hours and
calibrating three or four times a day for sensors.
