Repeated measures ANOVA was used to evaluate differences in scores of clinical scales (Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, International Staging System) across different time points (baseline, 2-week time point, 6-week time point). Bonferroni correction was applied for multiple comparisons. Results are reported as mean differences, standard errors, P values, and 95% confidence intervals. HDRS: Hamilton Depression Rating Scale; HAMA: Hamilton Anxiety Rating Scale; ISS: International Staging System; CI: Confidence interval.
