Fig. 4: FMTs have long-lasting effects on autism gut microbiomes.

a, The improvement of CARS for each child with ASD over time. The children were split into three groups—non-ASD, mild/moderate and severe—based on whether their CARS score fell below 30, was between 30 and 37 or was higher than 37. b, Microbial log fold changes over time: the time series was generated by calculating log fold changes between timepoints for each microbe. ASD-specific microbes highlighted in red were determined in the cross-sectional study. c–f, Microbial log fold changes are re-colored with genera highlighted in cytokine comparisons.
