Agreement on Day 1 against YSI Reference
The accuracy of GM versus YSI reference on the first day of sensor wear was assessed by calculating
the percentage of System readings that were within 15%, 20%, 30% and 40% for reference values
80 mg/dL and above, and 15 mg/dL, 20 mg/dL, 30 mg/dL and 40 mg/dL for values below 80 mg/dL
by hourly intervals. The results are presented in
Table 3
.
