Demographics, mood and anxiety questionnaire, and eating disorder scores in the three groups (M±SD, one-way ANOVA P-scores). Post-hoc differences between AN and HC indicated by *, between both AN and HC and AN-R and HC indicated by **. Where two groups were compared, P-Score is from independent samples T tests.
