  1. Note: AN_T1 participants with acute anorexia nervosa (mean duration of current AN episode: 10.65 months (standard deviation: 12.58)), AN_T2 participants with anorexia nervosa after partial weight restoration, HC healthy control participants, BMI-SDS body mass index standard deviation score, EDI-2 Eating Disorder Inventory, version 2; BDI-II Beck Depression Inventory, version 2.
  2. a44 AN participants were of the restrictive and nine of the binge-eating/purging subtype.
  3. bMean duration between assessments in AN patients was 81.57 days (range: 35–154).
  4. cIQ was only measured once in AN participants after weight gain.
  5. ***False discovery rate (FDR) < 0.001.
