the 7-day wear period, the sensors were calibrated with an average of 2 fingersticks per day
(approximately once every 12 hours), using self-monitoring blood glucose (SMBG) meter values. The
Original Pediatric Study used the LifeScan OneTouch Verio IQ meter; the Software 505 Pediatric
® ® ®
Study used Bayer's CONTOUR NEXT USB meter.
®
All subjects were evaluated in a controlled clinic environment on Day 1, Day 4 or Day 7 of the
7-day wear period. While using the System in the clinic, subjects provided at least two fingerstick
measurements per hour, and subjects ages 6-17 also provided venous blood for comparison to
a laboratory method, the Yellow Springs Instrument 2300 STAT Plus Glucose Analyzer. This
™
instrument is referred to as the "YSI." In the Original Pediatric Study, subjects' glucose levels were
not intentionally manipulated during this study; in the Software 505 Pediatric Study, subjects ages
13-17 had their glucose levels intentionally manipulated during the clinic session. Readings from the
System were reported every 5 minutes and paired with YSI values collected every 15 minutes in order
to characterize how well the System readings agreed with laboratory standard blood glucose results.
The remainder of the study took place at home, and the System performance was also paired with the
comparative meter results, referred to as the "SMBG."
