Percent time in different glycemic ranges for all subjects for outpatient collected data versus study day data as measured by CGM (A and B) and over the study day for all subjects as measured by CGM and YSI (C and D). No subjects experienced hypoglycemia, and they were in the safe range (80–180 mg/dL) for an average of 70% of the time, with a fraction of time in the mild hyperglycemia range and negligible time in the hyperglycemia range, as measured by YSI. *Statistically significant at P < 0.05.
