An ultra\u2010performance liquid chromatography\u2010mass spectrometry (UPLC\u2010MS)\u2010based metabolomics approach identified 72 differential metabolites after treatment. In addition, the baseline levels of methyl n\u2010formylanthranilate (MNFT) were correlated with the rate of reduction in the positive subscore or PANSS total score. However, increase in MNFT after treatment was not associated with the rate of reduction in the PANSS total score or its subscores. Subsequent regression analysis revealed that the baseline MNFT levels predicted the treatment outcomes after olanzapine monotherapy for 4\u2009weeks in patients with
