The clustering rate, proportion and linkages analysis in different age groups. (A) Clustering rate in molecular networks of different age groups. (B) The proportion of different age group among not-clustered cases, small/medium clusters and large clusters. (C) Linkages analysis of different age groups with the main HIV-1 subtypes in the network. The colour indicates the different age groups.
