^a)Duke Abdominal Assessment Scale [25]

Percentages refer to the proportions of all 202 respondents. No significant differences between subgroups were detected

Findings suggested in free text: “grey abdomen” (1), ascites (2), and thickened bowel wall (1). The first may correspond to featureless or multiple separated bowel loops, i.e. 5p on the DAAS, the latter two to separation of intestinal loops
