BM: Bowel movement; BSFS: Bristol Stool Form Scale; GIQLI: Gastrointestinal Quality of Life Index. BM frequency in number of BM/week. Table 5 shows unadjusted p-values. The p-value for the effect of ‘Diet’ on GIQLI was no longer significant after adjustment for multiple hypothesis testing.
Results of repeated measures ANOVA results are given for baseline vs 8 weeks, wherein the effects of vegan and meat-based diets were expectedly maximal.
