Mean Absolute Relative Difference (MARD) is a standard metric used to evaluate the accuracy of continuous glucose monitoring systems, [1] which gives the average amount a CGM sensor …

One of the analytic metrics to assess the accuracy of sensors is mean absolute relative difference (MARD).

Feb 18, 2025 · MARD (Mean Absolute Relative Difference) Feb 18, 2025, 10:52 A measure of CGM accuracy that compares sensor glucose readings to reference blood glucose values …

The MARD (Mean Absolute Relative Difference) measures the average difference between a device measurement (or test result) and the reference measurement at normal to high glucose …

Feb 29, 2024 · Mean absolute relative difference or MARD, as its commonly referred to, is a numeric metric used to describe the accuracy of a glucose sensor at a single point in time.

Accuracy of CGM systems can be provided as a value called MARD. Find out more about how MARD calculates accuracy of glucose monitoring systems.

The mean absolute relative difference (MARD) parameter is used most often to characterize the measurement performance of systems for continuous glucose monitoring (CGM).

Oct 5, 2024 · Conclusions: Using MARD to describe sensor accuracy has significant limitations, as a difference in study design (alone) can increase/decrease a MARD value. It has led many …

Jun 20, 2025 · Using raw CGM data, a dynamic, patient-specific algorithm was developed to minimize MARD through time lag optimization and linear modeling. The algorithm was …

CGM accuracy is often measured by MARD (mean absolute relative difference); the lower the MARD, the higher the accuracy. With a MARD of 8.0%, Dexcom G7 15 Day is the most …
