Figure 1

Causal Directed Acyclic Graph (DAG) of the assumptions made for the causal mediation analyses. H. suis denotes the presence of the bacterium in the fundic and pyloric gland zones, based on the qPCR assay. F. gastrosuis denotes the presence of the bacterium in the pars oesophagea based on the qPCR assay. The pars oesophageal microbiome is quantified by either its Shannon diversity index or the Amplicon Sequence Variant (ASV) counts of individual taxa. Due to their collinearity, the feed type is fully captured in the barn variable. The presence of erosion was defined as a macroscopic lesion score higher than two.
