Frequency of responses to each item of the FreKAQ-J.
Fig 1.
Persons of lesser disturbed body perception and items easier to endorse are located on the left side of the logit scale (ie, < 0 logits); Persons of higher disturbed body perception and items of greater difficulty to endorse are located to the right of the logit scale (ie, > 0 logits). Item endorsability mean is set at 0 logits by default.

The dashed line shows a trend-line through the mean of both sets of items, and the black lines show the upper and lower 95% confidence bands.
