Table of Demographics for healthy control (HC) and first episode psychosis (FEP) groups. FEP patients are separated by diagnosis into Schizophrenia and Other Psychosis. The study included 280 individuals. Schizophrenia patients were found to be slightly younger than controls and other patients. No significant difference was found for Gender, Ethnicity, PANSS scores or Anti-psychotic type. Pvalues were calculated using the chi-square test for categorical variables, and t-test for continues variables.
