  1. OTUs are ranked according to their normalised degree and unweighted betweenness scores. A total of 20 nodes were maintained in the positive graph once low scoring correlations were removed. OTUs identified as Escherichia and Streptococcus are highlighted. Note that scores could not be calculated for OTU_01 due to its lack of edges in the network graph.
