TABLE 2. Glucose and Glucose Variability Metrics.

Metric	Description	Equation
interdaySD [6], [7]	Interday standard deviation of glucose
		Where N = total days, G= glucose value
interdayCV [7]	Interday coefficient of variation of glucose
intradaySD Mean [7]	Intraday standard deviation of glucose (mean across all days)
intradayCV Mean [7]	Intraday coefficient of variation of glucose (mean across all days)
intradaySD Median [15]	Intraday standard deviation of glucose (median across all days)
intradayCV Median [15]	Intraday coefficient of variation of glucose (median across all days)
intradaySD Standard Deviation [15]	Intraday standard deviation of glucose (standard deviation across all days)
intradayCV Standard Deviation [15]	Intraday coefficient of variation of glucose (standard deviation across all days)
CONGA24 [6], [16]	Continuous overall net glycemic action over 24 hours
GMI [10]	Glucose management indicator
HBGI [6], [7]	High Blood Glucose Index
LBGI [6], [7]	Low Blood Glucose Index
ADRR [7]	Average Daily Risk Range, assessment of total daily glucose variations within risk space
J-index [6], [17]	Measure of both the mean level and variability of glycemia
MAGE [6], [18]	Mean amplitude of glucose excursions (default = 1SD)	1.Local minima/maxima determined 2.Assess max/min pairs against SD 3.If difference from min to max > SD, mean is retained 4.Otherwise excluded
		Troughs are retained and summed
MGE [6]	Mean of glucose outside range (default = 1SD)
		Where # is set, default is 1 SD
MGN*	Mean of glucose inside range (default = 1SD)
MODD [7], [16]	Mean of daily differences in glucose
TIR [19]	Time spent in range (minutes), default = 1SD
TOR [19]	Time spent outside range (minutes), default = 1SD
POR [9]	Percent of time spent outside range
PIR [9]	Percent of time spent inside range, default = 1SD
eA1c [20]	Estimated A1c (according to American Diabetes Association)
meanG [16]	Mean glucose over all days
medianG [9], [10]	Median glucose over all days
minG [9]	Minimum glucose over all days
maxG [9]	Maximum glucose over all days
Q1G [9]	First quartile glucose value over all days
Q3G [9]	Third quartile glucose value over all days

*indicates previously unidentified metrics of glucose variability that are similar to clinically validated metrics
