Using modern genetico-mathematical methods (genetico-correlational analysis), the author made a comparative analysis of the findings from a clinico-genealogic study of two groups of probands--with torpid schizophrenia (192 families) and with manifest forms of schizophrenia (365 families). The results obtained confirm the validity of the clinical differentiation of torpid schizophrenia as one of relatively independent forms of schizophrenia.
作者运用现代遗传数学方法（遗传相关分析），对两组先证者——隐匿型精神分裂症患者（192个家庭）和显性精神分裂症患者（365个家庭）的临床系谱研究结果进行了比较分析。所得结果证实了隐匿型精神分裂症作为一种相对独立的精神分裂症形式进行临床区分的有效性。
