  2. aFor a significant post hoc difference both p < 0.01 and a Cohen’s d ≄0.50 were required.
  3. bBED was omitted from all analyses except for OBE and SBE since purging behavior and inappropriate compensatory behavior should not be present in the diagnosis. For the same reason RAN was omitted from the analyses of OBE and purging behavior and PD from the analyses of OBE. Also, groups with n < 10 were omitted.
  4. cηp2 has been calculated through a regular ANOVA, since it was not a possible option in the Welch analysis.
  5. dAnswers for ‘extreme fasting’ is 0 = no days, 1 = 1-2 days, 2 = 3-6 days, 3 = 7 days, 4 = 8-10 days, 5 = 12-13 days, 6 = every day.
