reading on your receiver or mobile app, these tables show you how likely it is that the
reading matches your blood glucose level (measured by YSI in the study).
For example, the total number of data pairs considered in the analysis was 47,261. Of
these, 94.6% of the sensor readings fall within ± 20 mg/dL of the YSI blood glucose
values < 70 mg/dL and within ± 20% of YSI blood glucose values ≥ 70 mg/dL.
