Psychiatric disorders occur almost three times more frequently in subjects with AB blood type compared to subjects with other blood types (OR 2.64; 95% CI 1.33–5.25), but no statistically significant associations were found between different blood groups and particular diagnostic categories of psychiatric disorders, ...
