NOTE:
CGM readings are within 40 to 400 mg/dL (2.2-22.2 mmol/L),
inclusive.
Table 11 is categorized within CGM glucose ranges. For readings less
than or equal to 80 mg/dL (4.4 mmol/L) the absolute difference in mg/dL
(mmol/L) between the two glucose results was calculated. For values
greater than 80 mg/dL (4.4 mmol/L) the absolute percent difference
(%) from the SMBG values was calculated. The percentages of total
readings within 15 mg/dL (0.8 mmol/L) or 15%, 20 mg/dL (1.1 mmol/L)
or 20%, 30 mg/dL (1.7 mmol/L) or 30%, 40 mg/dL (2.2 mmol/L) or 40%
