Frequency distribution of scores obtained for categorical variables of the Section III (‘reaction to palpation of the painful area’ and ‘intestinal motility’) by group and time points (Control Group at inclusion, C; Pain Group at different time points, T1 = at the inclusion in the study; T2 = after the administration of an analgesic drug; T3 = at recovery). Data are expressed as n (%).
