Trend Accuracy - Dexcom G6 Pro User Manual

Trend Accuracy

Trend accuracy explains how well the G6 captures the time-
dependent characteristics of glucose fluctuation.
The following examples quantify G6's Trend Accuracy:
1. When the G6 CGM rate of change is rapidly rising (≥ 2 mg/dL/min),
how often is reference glucose also rising? The answer is 71.3% of
the time for adults and 67.1% for pediatrics.
2. When the G6 CGM rate of change is rapidly falling (≤ 2 mg/dL/ min),
how often is reference glucose also falling? The answer is 98.0% of
the time.
3. When the G6 CGM rate of change is stable (≥ -1 mg/dL/min and ≤ 1
mg/dl/ min), how often is glucose changing rapidly (≥ 2 mg/dL/min
or ≤ 2 mg/dL/ min)? The answer is only 1.9% of the time.
