Two-sample t-tests and chi-squared tests were used to compare between-group differences in demographic and clinical characteristics. Pearson's correlation coefficients were calculated to assess the relationship between symptom severity and the strength of functional connectivity with the amygdala in patients with SAD. Pearson's correlation analyses were repeated without nine patients taking medications. In addition, we considered the potential influence of comorbid depressed mood by using partial correlation analyses with covariates of the BDI scores in the patient group. Hemispheric asymmetry of left and right amygdala rs-FCN was calculated as the difference in rs-FCN strength of the left vs. right amygdala. All statistical tests were two-tailed with a significance level of 0.05. Additionally, adjusted p-values for multiple correlations using a sequential Holm-Bonferroni procedure were considered.
