FNE: fear of negative evaluation; GCSA: global cortical surface area (mm²); GCT: global cortical thickness (mm); ICV: intracranial volume (mm³); SAD: social anxiety disorder; SE: standard error.

Main effects of (sub)clinical SAD, social anxiety (z-score) and FNE are corrected for age (centered), gender and family structure. Reported p-values are uncorrected for multiple comparisons.

^aUncorrected mean ± standard deviation.

^bCoefficients represent standardized values.

^cEffects of age and gender are reported for the models including (sub)clinical SAD, but are comparable to the effects of these covariates in the models including social anxiety (z-score) and FNE. Values of the covariates are reported in Supplementary Table 2.

^⁎Significant at uncorrected p-value of 0.05. ^** Significant at Bonferroni-corrected p-value.
