Cluster analysis aids in diagnosing diseases by analyzing laboratory and clinical data. This review explores its applications, methods, and effectiveness in disease subgroup detection and data reduction.

Area of Science:

  • Medical Informatics
  • Biostatistics
  • Computational Biology

Background:

  • Cluster analysis is a statistical method for grouping similar data points.
  • Its application in medical diagnostics, particularly with laboratory and clinical data, requires careful evaluation.
  • Understanding disease subgroups and reducing data complexity are key challenges in diagnostics.

Purpose of the Study:

  • To survey the utility of cluster analysis in the context of disease diagnoses.
  • To explore applications in identifying disease subgroups and reducing data dimensionality.
  • To critically review existing literature on cluster analysis in diagnostics.

Main Methods:

  • Review of hierarchical and partitioning clustering techniques.
  • Mathematical description of classification methods.

Related Experiment Videos

  • Critical analysis of 24 relevant publications from the last decade.

    • Main Results:

    • Cluster analysis shows potential for disease subgroup detection.
    • It can be effective for data reduction through structure identification.
    • Challenges and limitations of clustering methods in diagnostics were discussed.

    Conclusions:

    • Cluster analysis is a valuable tool for diagnostic research, particularly for complex datasets.
    • Further research is needed to optimize its application in clinical settings.
    • The review highlights the importance of appropriate methodology and interpretation.
