Table 4b: Concurrence Analysis by Glucose Rate of Change (Pediatric*; n=168)
* Includes children 6-17 years of age. No YSI measurements were obtained for children 4-5 years of age.
Alarm Performance
The tables in this section show the accuracy of the System’s Low and High Glucose
Alarms. The Alarm Rate tells you how often the alarm is right or wrong. The
Detection Rate tells you how often the System is able to recognize and notify you
about a low or high glucose event.
Low Glucose Alarm Performance
Tables 5a and 5b display the percentages for these parameters:
True Alarm Rate
Tells you: When you got a low glucose alarm, were you actually low?
Definition: Percentage of time the alarm issued and blood glucose was below the
alarm level within 15 minutes before or after the alarm.
False Alarm Rate
Tells you: Did you get a low glucose alarm that you shouldn’t have?
Definition: Percentage of time the alarm issued and blood glucose was not below
the alarm level within 15 minutes before or after the alarm.
Detection Rate
Tells you: When you were low, did you get a low glucose alarm?
