wear locations (Tables 1-B to 1-E) and categorized within YSI glucose ranges (Tables
1-F to 1-I). When you see a CGM reading on your receiver or mobile application, these
tables show you how likely that reading matches your blood glucose level (measured by
YSI in the study). These tables include overall pooled data from both G6 studies.
For example, the total number of data pairs considered in the analysis was 25,101. Of
these, 91.7% of the G6 readings fall within ± 20 mg/dL of the YSI blood glucose values
< 70 mg/dL and within ± 20% of YSI blood glucose values ≥ 70 mg/dL.
