    Cluster analysis can effectively classify patients into diagnostic groups, offering a convenient tool for empirical grouping. Despite limitations, its appropriate use provides valid diagnostic classifications.

    Area of Science:

    • Medical informatics
    • Biostatistics
    • Psychometrics

    Background:

    • Patient classification into diagnostic groups is crucial for effective treatment and research.
    • The utility of cluster analysis for diagnostic grouping is debated among researchers.
    • Comparison with other multivariate methods is needed to validate cluster analysis.

    Purpose of the Study:

    • To provide further evidence on the use of cluster analysis for patient classification.
    • To compare cluster analysis with alternative multivariate methods for diagnostic grouping.
    • To assess the validity of diagnostic groupings derived from cluster analysis.

    Main Methods:

    • The study involved a comparative analysis of cluster analysis against other multivariate statistical techniques.

  • Appropriate application of cluster analysis was emphasized.
  • Empirical data was utilized to form diagnostic groupings.

    • Main Results:

    • Cluster analysis, when appropriately applied, proves to be a convenient method for developing diagnostic groups.
    • The limitations often cited for cluster analysis do not invalidate the groupings it produces in such cases.
    • The findings support the utility of cluster analysis in comparative multivariate analyses.

    Conclusions:

    • Cluster analysis is a valuable and appropriate tool for establishing empirically based diagnostic classifications.
    • The perceived limitations of cluster analysis should not preclude its use in developing diagnostic groupings.
    • Further research should consider cluster analysis as a viable method in patient classification.
