Characteristics and functions of the gut microbiome in monozygotic twins with autism spectrum disorders of varying severity

Figure 2 Species composition analysis of severe monozygotic twins with autism spectrum disorder and monozygotic twins with autism spectrum disorder-mild groups. A: Venn diagram highlights the overlapping area representing shared operational taxonomic unit between the two groups; B: The alpha diversity of the severe monozygotic twins with autism spectrum disorder group (blue) and the monozygotic twins with autism spectrum disorder-mild group (orange); C: The beta diversity of severe monozygotic twins with autism spectrum disorder group (blue) and the monozygotic twins with autism spectrum disorder-mild group (orange). The distance between the two groups reflects their similarity. MZCo-ASD-H: Severe monozygotic twins with autism spectrum disorder; MZCo-ASD-L: Monozygotic twins with autism spectrum disorder-mild group; PLS-DA: Partial least squares discriminant analysis.
