iqrgvp

Inter-quartile range is a measure of glycemic variability defined as the difference between 75th and 25th percentiles.

Calculate different glucose variability measures,
including average measures of glycemia, measures of glycemic variability and
measures of glycemic risk, from continuous glucose monitoring data.
