Note. ARFID = avoidant/restrictive food intake disorder; AN = anorexia nervosa and atypical anorexia nervosa primarily restricting presentation; HC = healthy controls; S.D.= standard deviation; S.E.M= standard error of the mean; T0 = hormone levels after an 8+ hour overnight fast; significant p values at <.025 for the omnibus ANOVA and <.05 for group mean post-hoc comparisons are indicated in bold.
