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

Table 5 The paired sensor glucose and capillary blood glucose measurements were stratified into five zones

Zone	Percentage (%), n = 397
Zone A (clinical accuracy)	83.1
Zone B (no or benign treatment)	13.6
Zone C (overcorrection)	0.8
Zone D (dangerous failure to detect and treat)	2.5
Failure to detect hyperglycemia	1.0
Failure to detect hypoglycemia	1.5
Zone E (erroneous measurement)	0
