p-value for the gender distribution in the three groups was obtained using a x2test. p < 0.05 is considered significant. NC is healthy controls, OCD indicates the patients with obsessive-compulsive disorder, and SZ is Schizophrenia patient. PANSS, Positive and Negative Syndrome Scale. HARS, the Hamilton Anxiety Rating Scale; 24-HDRS, the 24-item Hamilton Rating Scale for Depression; Y-BOCS, the Yale Brown Obsessive Compulsive Scale.
