Differentially abundant families and genera. A Venn diagram of differentially abundant families between the groups. B Heatmap of differentially abundant families belonging to the class Clostridia. C Venn diagram of differentially abundant genera between the groups. D Heatmap of selected differentially abundant genera belonging to the class Clostridia. *FDR p < 0.05. **25 overlapping differential genera in PDAC common to both populations are shown in Table 3.
