Trend accuracy
Trend accuracy explains how well G7 captures the time-dependent characteristics of
glucose fluctuation.The following examples quantify G7’s trend accuracy:
1.
When the G7 rate of change is rapidly rising (> 2 mg/dL/min), how often is
reference glucose also trending up (>0 mg/dl/min)? The answer is 96.0% of
the time for adults and 94.2% for pediatrics.
2.
When the G7 rate of change is rapidly falling (< -2 mg/dl/ min), how often is
reference glucose also falling (< 0 mg/dl/ min)? The answer is 89.9% of the
time for adults and 92.9% for pediatrics.
3.
When the G7 rate of change is stable (≥ -1 mg/dL/min and ≤ 1 mg/dl/ min),
how often is reference glucose changing rapidly (> 2 mg/dL/min or < -2
mg/dl/ min)? The answer is only 1.9% of the time for adults and 1.3% for
pediatrics.
