Description: Comparison of gut microbiota composition between responders (R) and non responders (NR). (A) Heatmap of seven bacterial genera with statistically differential abundance in R (n ¼ 13) and NR (n ¼ 12) at baseline. (B) Histogram of two representative differentially abundant genera at baseline. (C) Histogram of Bifidobacterium longum and Prevotella copri at baseline (left) and T1 timepoint (right). Statistical analysis was performed by Mann-Whitney test. **p < 0.01, * p < 0.05.
