Concurrence of System and Laboratory Reference
Table 3-A (Original Adult Study), 3-B (Software 505 Adult Study), 3-C
(Original Pediatric Study) and 3-D (Software 505 Pediatric Study) are
categorized by ranges of CGM glucose readings. These tables describe, for
each range of CGM glucose readings, what percentage of paired YSI values
were in the same glucose range (shaded) or in glucose ranges above and
below the paired CGM readings. For example, based on the Software 505
