Studies of correlation between the duration of toxoplasmosis and the amount of personality factor shift

In the second set of experiments we searched for this correlation between the amount of personality factor shift and duration of toxoplasmosis. In the first and second studies the time of infection, was known from clinical records. For two other studies we only estimated the duration of latent toxoplasmosis on the basis of a level of specific anti-Toxoplasma antibodies. In all studies the effect of age of subjects was removed by statistic methods.
