Figure 2.
(A) Examples of scintiscans at 6 h, 24 h and 48 h in patients with evacuation disorder (DD) and slow transit constipation (STC). Note that delayed transit is also demonstrated at 48 h in the patients with STC and the retention of isotope in the left colon in patients with evacuation disorder. (B) Comparison of least square means (adjusted for gender and body mass index) of colonic geometric centre at 24 h and 48 h. The DD group is best distinguished from healthy controls at 48 h; transit is slower in the STC than DD groups at both 24 h and 48 h. (C) Distribution of geometric centres (median, IQR, 5th and 95th percentiles) at 24 h and 48 h in the different subgroups (n provided for each group). Note, however, that there is considerable overlap of overall transit in the DD and STC groups.
