Mean (bar) and individual (circle) expression ratio (ER) values for OXSR1 (A) and WNK3-1 (B) are shown for the subjects with schizophrenia grouped by potential confounding factors. Neither sex, diagnosis of schizoaffective disorder, suicide, antidepressant medication use at the time of death, use of benzodiazepines or sodium valproate at the time of death, antipsychotic medication use at the time of death, nor diagnosis of substance abuse or dependence at the time of death significantly affected OXSR1 (A) or WNK3-1 (B) transcript expression. Numbers in bars indicate the number of subjects with schizophrenia in each category.
