Differences in the relative abundance of specific microbial taxa among the four groups. (A) Significant differences in gut microbiota across the four groups at the phylum level. One-way ANOVA with a post-hoc Tukey-Kramer test was performed for statistical analysis. (B) Bacteroidetes/Firmicutes (B/F) ratios of the four groups. (C) The ternary plot presents the main differences in gut microbiota in the CON, MOD, and MTR groups at the genus level. Dot size indicates the relative abundance of the genera. (D) Relative abundance of the genera Bifidobacterium in the four groups. (E) Relative abundance of the genera Lactobacillus in the four groups. (F–I) Significant differences in gut microbiota between 5-HTP treated and untreated groups at the genus level. Wilcoxon rank-sum test was used for statistical analysis. Data are expressed as the mean and SD. p < 0.05 was considered statistically significant (*p < 0.05, **p < 0.01, and ***p < 0.005).
