BMI-SDS was used for statistical analysis instead of BMI because the former provides an index of weight to height ratio that is corrected for age and gender100, 101. Abbreviations: recAN = recovered anorexia nervosa patients; HC = healthy controls; IQ = intelligence quotient; BMI-SDS = body mass index standard deviation score; EDI-2 = Eating Disorder Inventory. Displayed are means ± standard deviations.
