(a) Correlation between CGMS and blood glucose values. The dotted line shows a linear regression trend line. (b) Difference between CGMS and blood glucose values in each pair of measurements. (c) Bland-Altman plot. CGMS versus blood glucose values. A straight line shows the mean difference between CGMS and blood glucose values, and the two dotted lines show ±2 standard deviations.
