Statistical Analysis
- Data transformation Data transformation applied to microbial abundance measurements prior to differential abundance testing (if any).
- relative abundances
- Statistical test

- Significance threshold p-value or FDR threshold used for differential abundance testing (if any)
- 0.05
Alpha Diversity
- Shannon Estimator of species richness and species evenness: more weight on species richness
- increased
- Inverse Simpson Modification of Simpsons index D as 1/D to obtain high values in datasets of high diversity and vice versa
- increased

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.
Abundance in Group 1: increased abundance in Responders
