Figure 3. Alteration of the gastric microbiota after HP eradication.

(a) Boxplot of the changes of HP relative abundance, Shannon index and phylogenetic diversity index before and after HP eradication. The black point indicates the sample, and the lines connected the paired samples of pre- and post-eradication. The meaning of box is the same with Fig. 2a. (b) Donut chart of major bacterial phyla in pre- and post-eradication samples, as well as normal control samples. (c) The barplot of significant OTUs with logarithmic LDA score. The OTUs were sorted according to the decreasing order of logarithmic LDA score. The taxonomic annotation of OTUs by RDP classifier was listed unless noted. The phylum column was colored according to phylum name.
