Figure 1 Relationship between SLEEP-50 scores and ESP scores.

Notes: Mean (SD) SLEEP-50 scores are shown for groups of people with different ESP scores (0–4). An ESP score >2 is a positive screen for having eating disorders and warrants further investigation of the subject. Significant differences from the group with an ESP score of zero (P<0.05) are indicated by *.
