Extended Data Fig. 2: Species-level sharing (Bray-Curtis).
From: Gut microbiome strain-sharing within isolated village social networks
A, The distribution of Bray-Curtis dissimilarity based on relationship type. The final two boxes contain the strain-sharing rates between individuals living in the same village without an identified relationship, and all pairs of individuals living in different villages, respectively. Data are represented as boxplots where the middle line is the median and the lower and upper hinges correspond to the first and third quartiles; the whiskers extend from the hinge to the largest or smallest value, but no further than 1.5 * IQR from the hinge. Median values for each distribution are at the top of each box. B, Observed Bray-Curtis dissimilarity for each relationship compared to 100 draws from a within-village relationship permutation. All observed relationships, except for close friends, have a significantly higher Bray-Curtis dissimilarity than the scrambled networks, with the adjusted P-value reported in each figure (two-sided Wilcoxon rank-sum tests). C, Bray-Curtis dissimilarity based on how often a pair spends free time together. D, Bray-Curtis dissimilarity based on how often a pair shares meals together. E, Bray-Curtis dissimilarity based on greeting type. The median values for each distribution in panels A, C-E are also reported at the top of each box.
