Effects of the physical distancing approach on the microbial co-occurrence networks. (A) The Venn diagrams show the number of shared/unique links or nodes between co-occurrence networks inferred without covariate (M0) or with the initial physical distance as covariate (M1). The nodes and links highlighted in bold correspond to those specifically related to the effect of the physical distancing treatment when comparing the M0 and M1 models. (B) For each network model and community, the number and proportion (out of the total number of links per model network) of positive (blue) and negative (red) links are represented. Links represent partial correlations ρ and they are colored blue if ρ > 0 and red if ρ < 0
