Background: Schizophrenia is associated with impaired antioxidant defense, including abnormal serum, plasma, and red blood cell (RBC) oxidative stress parameters. We performed a meta-analysis of these associations, considering the effect of clinical status and antipsychotic treatment after an acute exacerbation of psychosis.
Methods: We identified articles by searching PubMed, PsychInfo, and Institute for Scientific Information, and the reference lists of identified studies.
