Diversity and microbial features at the phylum level of the gut microbiome of pregnant women with ICP. A α diversity of the gut microbiome of subjects in the control, mild ICP and severe ICP groups expressed by the Shannon index. *** indicates a significant difference between groups (p < 0.001). B β diversity of the gut microbiome of subjects in the control, mild ICP and severe ICP groups expressed according to PCoA based on UniFrac distance. C Microbiome composition in different groups at the phylum level. The five most dominant phyla were Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria and Verrucomicrobia
