Meta-analysis of the bacteria significantly enriched in R and NR. a Heatmap showing the relative abundance of R-enriched and NR-enriched bacterial species, as identified by LEfSe. b Correlation network of the R-enriched and NR-enriched species (Spearman correlations with rho > 0.5, P < 0.01 were shown). The size of the nodes is proportional to the averaged relative abundance of these species in all samples. The thicknesses of the lines denote the strengths of the correlations. c Positive correlation network of the significant R-enriched species and KO categories
