*Using rescaled inventories: the Short Form 36 (SF-36), Hospital Anxiety and Depression Scale (HADS) anxiety and depression were divided by 2; Spence Children’s Anxiety Scale (SCAS) anxiety and pain were divided by 10 and fatigue was divided by 3. †Adjusted for age, sex and the other variables in the table.
