title: [Determination of diagnostic significance of nonspecific morphological signs].
abstract: For assessment of diagnostic significance of nonspecific morphological signs the authors suggest to apply calculation of their informativeness according to Kullback's formula. This qualitatively characterizes the degree of difference of crossed signs in differentiating diseases. An initial value is frequency of occurrence of a sign or a degree of its manifestation determined by a relative frequency index according to histometry findings. Calculation of informativeness may be applied only with respect to statistically significant differing aspects. The value of the informativeness index corresponds to diagnostic significance of a sign. The recommended objective method broadens the sphere of application of diagnostic biopsy and may facilitate putting into practice of pathological anatomy of methods of computer diagnosis.
