Comparison of digestive levels according to whether or not patients were treated with PPIs. As no normalization has been performed before PCR reaction, no significant conclusion can be supported regarding the density of the bacteria, the number of reads is indicated with informative value. Firmicutes: blue, Proteobacteria: red, Bacteroidetes: green, Actinobacteria: yellow, Fusobacteria: pink. Ai: aerointolerant, Ae: aerotolerant
