MARD

MARD is an acronym that can refer to several organizations and technical terms. The two most common uses are a government ministry in Iran and a statistical metric used in medical technology.

Ministry of Roads and Urban Development (Iran). The Ministry of Roads and Urban Development, abbreviated MARD, is a government ministry in Iran responsible for planning, policy, and regulation related to transportation infrastructure, roads, urban development, and housing. It oversees the national transportation network, urban planning, and related agencies, and plays a central role in infrastructure investment and housing policy. The ministry was formed through government reorganizations in the 2010s and operates within the executive branch under the president and parliament oversight.

Mean Absolute Relative Difference. In statistics and biomedical engineering, MARD stands for Mean Absolute Relative Difference, a measure of accuracy for continuous glucose monitors (CGMs). It is calculated as the mean of the absolute differences between CGM readings and reference glucose values, divided by the reference values, typically expressed as a percentage. Lower MARD indicates closer agreement with reference measurements, and it is used to compare CGM performance across devices and studies.

Other uses. MARD can denote other organizations, initiatives, or concepts in different languages or domains. As an acronym, its meaning is usually clarified by context.
