Comparison of anti-Toxoplasma antibody-positivity rates between psychiatric patients and the general population in different age groups. Compared with the general population, psychiatric patients in the 21–40 years old age group (OR = 2.174 95% CI 1.290–3.664, p = 0.004) and 41–77 years old age group (OR = 5.405 95% CI 1.291–22.637 p = 0.021) had a higher positivity rate of anti-Toxoplasma IgG antibody.
