A: Accuracy analysis. The 379 pairs of glucose values were plotted against each other with the meter on the x-axis and CGMS on the y-axis. The graph was divided into four areas by a line crossing the value of 60 mg/dl on each axis. The areas were labeled as true positive (TP), true negative (TN), false-positive (FP), and false negative (FN), respectively, depending on where the point fell on the graph. The number of true positive was 26, true negative 339, false-positive 3, and false negative 11. B: Clarke error grid analysis. A total of 379 paired values were plotted using the Clarke error grid. Of the values, 97.4% fell within the clinically acceptable A and B regions (n = 369), 81.3% fell in zone A, and 16.1% in zone B. Only one measurement fell in the upper C region (0.3%) and nine in the upper D region (2.3%).

Pie chart depicting the glycemic trends obtained from the CGMS during a 24-h period. Each portion corresponds to a glucose range. The legend below the figure depicts the different ranges. The proportion of the time spent within any given range is expressed as a percentage and shown next to each portion.
