Detecting interaction networks in the human microbiome with conditional Granger causality
Fig 2
Number of strong coefficients of Granger causality for interspecific (left column) and intraspecific (right column) taxon pairs in the gut, and on the left-hand, right-hand and tongue.
For a given response variable (taxon), the total number of significant coefficients of each predictor taxon was noted. Plots were created by the totality of such coefficients for all response variables. Inset pie-charts show the fraction of taxa with (colored) and without (black) at least one significant predictor.
