Mean amplitude of glycemic excursions (MAGE), together with mean and standard deviation (SD), is the parameter for assessing glycemic variability and is calculated based on the arithmetic mean of differences between consecutive peaks and nadirs of differences greater than one SD of mean glycemia. It is designated to assess major glucose swings and exclude minor ones.
