Fig. 4. Supplementation influences microbial interactions. (a) Density of microbial interactions, 822 calculated as significant correlations among microbiota (edges) normalized by the numbers of taxa 823 (nodes), by nutritional status, supplementation arm and place of residence (site). Lighter and darker 824 hues represent samples from 12 and 24 months respectively. (b) Proportions of significant 825 microbial interactions occurring cross-kingdom, within indicated sample groups. (c) Degree 826 distribution and (d) betweenness centrality scores of microbial networks in 12 month old children 827 grouped by nutritional status and supplementation arm. (e) Graphic representations of 828
