Contact networks have small metric backbones that maintain community structure and are primary transmission subgraphs

Community structure comparison for the French high school (Fr-HS) dataset using Sankey plots.
(A) Comparison of metalabels—student attribution to their classes—with modules detected on the original graph. (B) Comparison of the modules detected on the original graph with those detected on its metric backbone subgraph. (C) Comparison of the modules detected on the original graph with those detected on the threshold subgraph of same size as the metric backbone. (D) Comparison of the modules detected on the original graph with those detected on a random subgraph of the same size as the metric backbone. Metalabel module colors assigned to student specialization and classes as in Fig 1A–1C. Modules computed using the Louvain algorithm [49].
