Includes children 6-17 years of age. No YSI measurements were obtained for children 4-5 years of age.
Sensor Accuracy Over Time
The Sensor can be worn for up to 14 days. The percentage of System readings within YSI values and
the Mean Absolute Relative Difference (MARD) is presented for the following different wear periods
in
Tables 6a and 6b
: Beginning (Adult: 144 Subjects, Day 1, 2 or 3; Pediatric: 48 Subjects, Day 1
or 2) Early Middle (Adult: 91 Subjects, Day 7 or 8; Pediatric: 50 Subjects, Day 7 or 8), Late Middle
(Adult: 55 Subjects, Day 9 or 12; Pediatric: 51 Subjects, Day 9 or 12), and End (Adult: 76 Subjects, Day
13 or 14; Pediatric: 51 Subjects, Day 13 or 14). For values 70 mg/dL and above, the percentage of
readings within 15%, 20%, and 40% of the YSI value was calculated. For values below 70 mg/dL, the
percentage of readings within 15 mg/dL, 20 mg/dL, and 40 mg/dL of the YSI value was calculated.
