FIGURE 4.

Proportions with delayed, normal and rapid colonic transit in diabetes patients with constipation, without constipation and in healthy controls. Frequencies are given as n (%), where percentages are calculated from the total n in each group. Constipation (n = 15): 7 (47%) delayed; 6 (40%) normal; 2 (13%) rapid. Without constipation (n = 42): 17 (41%) delayed; 21 (50%) normal; 4 (10%) rapid. Healthy controls (n = 23): 2 (9%) delayed; 20 (87%) normal; 1 (4%) rapid. Proportions were equally distributed in the diabetes groups (p = 0.75), both differing from the distribution in healthy controls, p = 0.01
