Forest plot of mean differences in total (A), psychosocial (B) and physical (C) domains of HRQOL between the disordered eating group and the non-disordered eating group HRQOL measures: The PedsQL 4.0 in the studies by Mitchell and Jalali-Farahani, 2015; The KINDL-R in the study by Herpertz-Dahlmann, 2008 Disordered eating variables: The Mitchell study used the total score of six-point Likert scale variable of disordered eating, the mean difference represents the decrease in QOL for one unit increase in the disordered eating; Jalali-Farahani, 2015 and Herpertz-Dahlmann, 2008 used dichotomous variable of disordered eating (with and without disordered eating behavior). Std: standardized; SD: standard deviation; CI: confidence interval.
