Causal roles of gut microbiota in cholangiocarcinoma etiology suggested by genetic study

Figure 4 Scatter plots of causal estimates of specific gut microbiota taxa on intrahepatic cholangiocarcinoma. The slope of each line corresponding to the estimated Mendelian randomization effect in different models, including the conventional inverse variance weighted, weighted median, simple mode, and weighted mode. A: Family Veillonellaceae; B: Genus Alistipes; C: Order Enterobacteriales; D: Phylum Firmicutes; E: Genus Anaerostipes; F: Genus Paraprevotella; G: Genus Parasutterella; H: Phylum Verrucomicrobia. MR: Mendelian randomization; SNP: Single nucleotide polymorphisms.
