The table shows the results of ANCOVA, i.e., the significance and effect size (eta², which is approximately equal to the fraction of variability of a dependent variable explained by the variability of an independent variable) for mental and physical health and psychiatric symptoms. For the factor toxoplasmosis, the effect size was also shown as the Cohen's d. The last two columns (toxo*) show the result of ANCOVA in which not only age and urbanization, but also physical health, were controlled. The p value < 0.00005 is coded as 0.000; the associations significant after the Benjamini-Hochberg correction for multiple, five or six (the last ANCOVA analysis) tests are printed in bold.
