[Multidimensional analysis in clinical investigation. Application to the pathogenic classification of idiopathic hypercalciuria].

Multidimensional analytical techniques enable any number of variables to be studied simultaneously. These techniques have been described and a few examples of their application to biomedical research given. A classification of so called "idiopathic hypercalciuria" was made using this approach which demonstrated the existence of three possible mechanisms of pathogenesis.
