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

Figure 2 The forest plot illustrates the relationships between gut microbiota and cholangiocarcinoma. A: An increased abundance of gut microbial taxa was observed to be linked with a reduced risk of cholangiocarcinoma (CCA); B: An increased abundance of gut microbial taxa was observed to be linked with an elevated risk of CCA. OR: Odds ratio.
