Abstract
Continuous glucose monitoring (CGM) provides detailed information about the course of glycaemic changes during the day, which allows for a much more accurate setting of insulin therapy. Also, it offers new parameters, which can then be used in clinical practice to assess the degree of compensation for diabetes.
The strongest indicator of glycaemic compensation is the percentage of time spent in the target glycaemic range, the so-called time-in-range (TIR). It is considered to range from 3.9 to 10 mmol/L.
Since 2019, there have been specific TIR recommendations for different groups of diabetic patients (type 1 and type 2 diabetics, pregnant diabetics, and at-risk/fragile patients) that allow CGM results to be interpreted on a more individual basis.
