Fig. 3: Microbiome strain-sharing across two time points.
From: Gut microbiome strain-sharing within isolated village social networks
a, Strain-sharing between pairs of people across two time points roughly 2 years apart in four villages (n = 301). A tie between two people is drawn if a relationship between them is discerned at time point 1, coloured in blue if the strain-sharing rate is above the median strain-sharing rate of the village at the first time point, otherwise grey. b, Standardized coefficients and s.e. (as bars) from the linear mixed-effect model; the primary coefficient of interest is for whether there is a ‘relationship’ (social connection) between the pair of people or not indicating that connected people come to share more strains over time than unconnected people in the same village (linear mixed model n = 14,268; two-sided Satterthwaite’s t-tests: strain-sharing rate at T1, P < 2 × 10−16; relationship, P = 7.6 × 10−12; Mahalanobis distance, P = 6.4 × 10−4).
