System Glucose Availability
The System is designed to generate a GM value every 15 minutes throughout the sensor wear time. Overall, 202
sensors were inserted. 167 sensors produced glucose readings and are included in the analysis. There were
35 sensors that failed at insertion (i.e. no glucose reading generated) and are not included in the analysis. There
were 62.5% of primary sensors that worked for 14 days. The mean sensor duration for all primary sensors was
determined to be 258 hours, and the median duration of was 327 hours.
Table 14 shows the number of available glucose readings reported by all sensors (by sensor operational hour)
that produced at least one GM reading during the clinical study over the 14-day wear period. The percentage of
available GM readings is presented in comparison to the number of expected GM readings based on the number of
hours of sensor wear. Overall, 96.9% (153,169 GM readings out of expected 158,052) of GM readings were available.
