Figure 1

Dot plots of plasma intact fibroblast growth factor 23 (iFGF23) levels in bulimia nervosa (BN) patients with a high frequency of binge eating (HF group), BN patients with a low frequency of binge eating (LF group), and healthy controls. The graphs show median values (bars). The two-tailed Mann-Whitney U-test with Bonferroni's correction was used to assess the significance of differences among groups. A value of p < 0.017 was considered statistically significant. *p < 0.017 vs. LF group. **p < 0.001 vs. controls.
