FIG 2.
Relative abundance of Coprococcus and Prevotella for each study-site location in individuals with and without ASD. Box and whisker plots are colored by study site and grouped by ASD status with Coprococcus on the left and Prevotella on the right. Individuals in CO had lower levels of Coprococcus (Kruskal-Wallis, χ2 = 4.17, P = 0.041) and higher levels of Prevotella (Kruskal-Wallis, χ2 = 6.18, P = 0.013) compared to those of individuals in AZ. ASD status was not significantly related to relative abundance of either genus. AZ, Arizona; CO, Colorado; ASD, autism spectrum disorder.
