Note: The overall number of available paired SG-YSI points on FST Day 1 was from 83 subjects.
Percent agreement post calibration
The agreement of the SG values to paired YSI values was assessed for every 2-hour
period post sensor calibration. For readings less than or equal to 80 mg/dL, the
absolute difference in mg/dL between the SG and paired YSI values was
calculated.
