NOTE: CGM readings are within 40-400 mg/dL (2.2-22.2 mmol/L),
inclusive.
Table 1-A is categorized within CGM glucose ranges. When you see
a CGM reading on your receiver, this table shows you how likely that
reading matches your blood glucose level (measured by YSI in the
study). For example, if your CGM reads 100 mg/dL (5.6 mmol/L), it is
