[Results of a clinico-statistical study of the course of unremitting paranoid schizophrenia].

Statistical regularities characterizing the temporal distribution of the transitions of continuous paranoid schizophrenia from from stage to stage were studied on a random epidemiological material. It has been shown that the mechanism responsible for those transitions has, in principle, a probability nature, and the distribution as such can be described by a sole parameter which is a value expressing the probability of the disease transition to the next stage within a time unit. It has been also shown that this parameter can serve as a measure of the disease progress.
