Objective: To explore shared pathogenesis between schizophrenia and polycistic ovary syndrome (PCOS).
Methods: Ninety-six studies of schizophrenia and PCOS from a mean sample of 139 women are recruited from PubMed and FASTSTATS for geometrical regression analysis. Parametric and observational properties of both diseases (gene polymorphism, monoamines, gonadal steroids, gonadotropins, thyroid hormones, insulin sensitivity index, hirsute index, oligomenorrhea, anhedonia, asociality, apathy, emotional withdrawal, alogia, poor rapport, stereotypical thinking, hyperkinetic reactions, treatment with valproate) are stochastically distributed in the elliptical area.
Results : Results of both analyses suggest that insulin resistance and elevated testosterone are predictive to comorbidity. These associations are stronger with calculation from elliptical model (r 2 = 0.92) than a traditional regression analysis (r 2 = 0.65).
Conclusions: Insulin resistance and elevated testosterone in women contribute in shared pathogenesis of schizophrenia and PCOS. 3D regression analysis shows greater strength of association with the “criterion” value.
