The plasma concentration of cholecystokinin (CCK) before and at different time points after an injection of 0.2 μg/kg body weight of CCK-8. There were 11 subjects in each group. Values are given as mean and standard error of the mean (SEM). When calculating the area under the curve (AUC), there was a significantly increased AUC in the colectomised subjects compared to controls (p < 0.04). No difference was seen between the groups when comparing values at each time point. Wilcoxon signed rank test. = control, = patient.
