Alpha diversity index box plot. The community richness between early CD groups, advanced CD groups and control groups was showed as A (observed species diversity index) and B (chao1 index) and the species diversity of microbiota was showed as C (Shannon diversity) and D (Simpson diversity index). The horizontal axis represents the sample grouping, and the vertical axis represents the Alpha diversity index value of different groups.
