Figure 4. (A) Linear discriminant analysis effect size of gut microbiota in the NCG and OG. Red represents increased microbial abundance in the NCG; green represents increased microbial abundance in the OG. (B) The correlations among different taxa from the phylum to species levels are shown in the cladogram. (C) Heatmap showing differential bacterial genera. (D) Histogram of the top 10 differential bacteria at the genus level. Wilcoxon test (P < 0.05; n = 7).
