Distribution of the predominant bacteria at the phylum and genus levels in five datasets. a Stacked bars of the microbial composition at the phylum level among HC, CHB, LC and HCC. b Bar chart of the relative abundance of predominant taxa at the phylum levels in LC and HCC compare to HC. Wilcoxon rank sum test was used to compare the difference. *: p < 0.05, **: p < 0.01, ***: p < 0.001. c Stacked bars of the microbial composition at the genus level among HC, CHB, LC and HCC
