Computerized method for the graphic representation of multivariate periodontal data.

Appreciation of the multivariate features of data from periodontal research studies is sometimes difficult. This appears to be due to the form of tables and graphs in which information is made available in published studies. A computerized graphical technique, which appears well suited to the multivariable situation, is described. It uses structural analogy between the measurement scales and the variables measured and provides what can be a compelling iconic description of multifaceted data.
