  1. ITAC interferon-inducible T cell alpha chemoattractant, MADRS Montgomery–Asberg Depression Rating Scale, S.E. standard error, CI confidence interval.
  2. There were two blocks of independent variables in this linear regression model, the first block included age, gender, BMI, dose of antidepressant, and combined use of mood stabilizer/benzodiazepine/antipsychotic, and the second block included cytokines that were significantly correlated with reduction in MADRS on day 13.
