Background:

The multivariate reference region (MRR) is a statistical tool proposed over 30 years ago.
Its clinical utility and practical value remain subjects of ongoing discussion and investigation.

Purpose of the Study:

To critically review the mathematical underpinnings of the MRR.
To explore current and potential clinical applications of MRRs.
To evaluate the advantages and disadvantages associated with MRR use.

Main Methods:

Review of the theoretical mathematical framework of MRR.
Analysis of published clinical studies and applications involving MRRs.
Discussion of practical considerations, benefits, and limitations.

Main Results:

The theoretical basis of MRR is well-established.
Clinical applications are diverse but often lack definitive validation.
Significant advantages exist, but practical disadvantages and interpretive challenges persist.

Conclusions:

The clinical value of MRR requires further rigorous investigation and standardization.
Future research should focus on refining MRR methodologies and validating their impact on patient outcomes.
Clarifying the role of MRR in clinical practice is essential for its effective adoption.
