An analysis of the mean percentage of Absolute Relative Error (ARE percentage) and standard deviations,
across 12-hour increments of wear periods, appears in the table below. Both data sets are pooled together
in this data.
Hours From Insertion Mean ARE (%) Std. Dev.
0-12 hrs 24.84 20.04
12-24 hrs 19.66 16.17
24-36 hrs 16.43 15.62
36-48 hrs 18.23 19.27
48-60 hrs 16.59 14.25
>60 hrs 22.95 23.51
The median sensor life from Data Sets A and B were 57.5 hours and 72.9 hours, respectively. Twenty-one
of the sensors operated for 72 hours, while the others were removed for a variety of reasons, most often
because of calibration errors.
