The two time points in which the positive control was tested on the same experimental day differed only in terms of number of contractions of the diverticulum (control 1 = 1.48 ± 2.32, control 2 = 2.48 ± 2.04; Wilcoxon: Z = −1.992, p = 0.046), with the second control being higher, while its intensity showed a trend in the same direction (control 1 = 2.4x10 6 ± 4.6x10 6 , control 2 = 4.0x10 6 ± 5.2x10 6 ; Wilcoxon: Z = −1.894, p = 0.058).
