Figure 1.

ISO-modified Bland–Altman plots for the (A) GluCath IA-CGM system and (B) FreeStyle SC CGM system. The x-axis represents the average of sensor and reference glucose measurements in mg/dl. The y-axis represents the absolute difference between sensor and reference glucose measurements in mg/dl. The solid line represents the mean difference (GluCath −8.6 and FreeStyle −8.0 mg/dl); dotted lines are drawn at the mean difference ± 1.96 times the standard deviation of the mean difference. The long dashed lines represent the ISO-15197:2003 criteria.
