Concurrence of System and Laboratory Reference
The percentage of concurring CGM readings and YSI reference values
were included in Table 3. For example, when CGM readings are within
81 to 120 mg/dL (4.4-6.7 mmol/L), you can expect your blood glucose
levelsarewithin40to60mg/dL(2.2-3.3mmol/L)2%oftime;within
60to80mg/dL(3.3-4.4mmol/L)17%oftime;within81to120mg/dL

of time.
Table 3 is categorized by each range of CGM glucose ranges. This table
describes for each range of CGM glucose readings, what percentage
of paired YSI values were in the same glucose range (shaded) or in
