Reactivities of antibodies to T. gondii antigen in the sera of different age groups. The sera from clinically healthy group (blue) and psychiatric patients (green) were divided based on the age of each individual and the OD values from all samples in each group with specific reactivity were presented. Bars stand for 50% OD values of each group, lines below and above each bar stand for 25% OD values. The black lines in the bars stand for the median OD value. Samples with much higher or extreme OD values excluded in the statistical analysis are indicated with circles and asterisks.
