Table 2. GW2B Accuracy Summary Statistics.

(N=3,672 paired GW2B-reference glucose values)

	Mean (95% confidence interval)	Median (25^th, 75^th percentiles)
Difference mg/dL^*	2.2 (−2.0, 6.1)	3 (−19, 26)
Absolute Difference mg/dL^†	30.9 (28.7, 33.2)	23 (11, 42)
Relative Difference^‡	6% (4%, 9%)	2% (−12%, 20%)
Relative Absolute Difference^§	22% (20%, 23%)	16% (7%, 29%)

Difference is the sensor glucose value minus the reference value.

^†

Absolute Difference is the absolute value of the difference.

^‡

Relative Difference is the difference divided by the reference value (expressed as percentage).

^§

Relative Absolute Difference is the absolute difference divided by the reference value (expressed as percentage).
