MetaPop’s microdiversity analyses reveal lower intra-population diversity in autistic children. Boxplots showing median and quartiles of A Shannon’s H, B average nucleotide diversity (π), and C the average number of genomes under selection in pre-FMT autistic and neurotypical children. The Wilcoxon’s test p-values above are the result from comparing pre-FMT autistic and neurotypical children values. D Connected dot plot showing the average π for the autistic children pre-FMT and post-FMT. The color filling the circle represents the pre- and post-FMT status and the outlier color of the circle represents the method in which the FMT was delivered (oral or rectal delivery). The colored squares next to the autistic child’s ID corresponds to whether the child responded or did not respond to the FMT treatment
