Comparison of source attribution (left panel) and threshold distance clustering (middle and right panel) applied to one same cluster from simulated coalescent tree. The initial sample comprised 62 individuals forming a cluster at threshold 5%. The node positions, colours, and shapes are the same for all networks. For the SA graph, width of links is proportional to square root of the infector probability. Infector probabilities < 0.1% are not shown. Colour represents age category at time of diagnosis (darker colours represent older patients). Triangle nodes represent patients in early HIV infection, circles represent chronic stages and square nodes represent AIDS stage at time of diagnosis. Node size is proportional to square root of out-degree. For the clustering graphs, the single-linkage algorithm was re-applied to the sample with a genetic distance threshold of 0.5% or 1.5%.
