Regarding Relationships, the toxoplasmosis–sex interaction effect was marginally non-significant ( p = 0.053); uninfected men scored higher than infected men, but no difference was observed between infected and uninfected women.
Specifically, authors demonstrated lower scores in three out of the four subscales of this scale, namely Impulsiveness and Disorderliness (both significant) and Extravagance (approaching significance, p = 0.056) than the controls.
A more recent review, drawing on meta-analytic evidence, suggested that Toxoplasma infection might be a risk factor for the development or worsening of autism symptoms, but the reported odds ratio (1.53) did not reach statistical significance ( p = 0.079), thus leaving room for further clarification [ 154 ].
A large cross-sectional study conducted on data from 2619 non-clinical subjects found a non-significant positive association between Toxoplasma seropositivity and drug addictive disorder in men (odds ratio = 3.29, p = 0.01) and a negative trend for women (odds ratio = 0.51, p = 0.32) [ 185 ].
