Accuracy and feasibility of initiating real-time continuous glucose monitoring in noncritically ill hospitalized patients with type 2 diabetes

Figure 2 Clarke Error Grid Analysis of paired sensor glucose and capillary blood glucose measurements. The paired sensor glucose and capillary blood glucose measurements were stratified into five zones. Overall, 96.7% of data points fell within zones A and B, which are considered clinically acceptable. Overcorrection of high glucose levels occurred in 0.8% of measurements (zone C). Failure to detect hypoglycemia and hyperglycemia occurred in 1.5% and 1.0% of measurements, respectively (zone D). No erroneous measurements were observed (zone E).
