^aFDR = false discovery rate; PC = principal coordinate

^bEDEQ refers to the total score on the Eating Disorder Examination-Questionnaire. The following subscales are also included: Dietary Restraint (Restraint), Eating Concern (EatingC), Shape Concern (ShapeC), Weight Concern (WeightC)

^cAlpha = 0.05; FDR level = 0.1

^dAssociations were examined with the tau-b correlation coefficient.
