*
Fisher’s exact test used for right colon, mid colon and rectosigmoid components due to small expected cell counts, χ2 test used for fluid content, Mann-Whitney U test used for total score;
†
Data presented as n (%) for right colon, mid colon, rectosigmoid and fluid components, and median and interquartile range (IQR) reported for total score;
‡
Total score = composite of right colon, mid colon, rectosigmoid and fluid: lower scores = better, higher scores = worse)
