Microbial influence networks for a dMMR and b pMMR microbial communities. Node size indicates a microbe’s metabolic influence over other microbes. Edges, which are directional and weighted according to the magnitude of their influence, indicate how one microbe affects the growth rate of another. Grey edges indicate a positive interaction, i.e., predicted increase in growth when paired, while red edges indicate a negative interaction, i.e., predicted suppression in growth when paired
