Objective GI outcomes which were reported most frequently are presented for all eating disorders together (ED), Anorexia nervosa (AN) and Bulimia nervosa (BN). The number (n) and percentage (%) of studies reporting the specific GI outcome are shown. GI symptoms presented for ED are not the calculated sums of separate EDs shown in this figure. It is the summary of studies shown in Supplementary Material Table 1 which assessed more than one ED.
