Dietary fibre shapes the baseline gut microbiome when tumours reached 50 mm3. a Stacked bar plot of phylogenetic composition of common bacterial taxa at the species level when tumours reached 50 mm3. Faeces were collected from mice fed with low-fibre, low-fibre with butyrate, high mixed fibre, high insoluble fibre, and high soluble fibre diets (n = 3 for each group). b Shannon’s index of gut microbiomes by the Kruskal-Wallis test. Error bars represent the interquartile range of diversity scores. c Principal coordinate analysis of gut microbiomes using the Bray-Curtis dissimilarity. A notable clustering effect by diet was seen in the gut microbiome. d Differentially abundant taxa when the tumours reached 50 mm3. All comparisons among different diet groups were performed by the Kruskal-Wallis test and Dunn’s multiple comparison tests. All tests compared each median with the “control” denoted. The diet with the highest abundance of taxa was denoted as the control. *p < 0.05; **p < 0.01; ***p < 0.001
