CONTINUOUS GLUCOSE MONITORING SYSTEM
AGREEMENT
Agreement between the Seven System and blood glucose levels is characterized using
paired Seven System and YSI results. e Seven System and YSI readings were compared
by pairing the Seven System reading that fell within 2.5 to 7.5 minutes after the YSI
reading was collected.
e agreement of the Seven System to blood glucose levels was assessed by calculating
the percentage of Seven System readings that were within 20%, 30%, and greater than
40% of the YSI readings. For readings less than or equal to 80 mg/dL the difference in
mg/dL between the two glucose readings was calculated. For readings greater than 80
mg/dL the percent difference (%) from the YSI reading was calculated. e percentages
of total readings within 20 mg/dL or 20%, 30 mg/dL or 30%, or greater than 40 mg/dL or
40% were then calculated. e total number of data pairs considered in this analysis was
2,318. Results are shown in Table 1.
