Network visualization of Spearman rank correlations from log transformed data with values > 0.60 and < −0.60 calculated of the variables with PCA loadings > 0.60 and < −0.60 for the pasture-finished (a) and pen-finished (b) groups separately, and (c) pen-finished data subtracted from the correlations of the pasture-finished data. Red color of the edges represents positive correlations with darker red representing higher correlations. Blue represents negative correlations, with darker blue representing higher correlations. Thickness of the edge represents strength of the correlation. The node size represents the degree of the nodes. Groups of related metabolites are marked by the dashed circles
