β values represent the negative log of the prevalence ratio between bulimia nervosa and the remaining eating disorders (anorexia nervosa, binge-eating disorder, and other specified feeding or eating disorder). Ratio and proportion are reported for 50% female population at the mean mid age of 25·5 years (SD 16·2). Percentage female was centred at 50% female, and mid age was mean centred. UI=uncertainty interval.
