Connectivity of UN subregions during dispersal of Mycobacterium tuberculosis. The Bayesian stochastic search variable selection method was used to identify and quantify migrations with strong support in discrete phylogeographic analysis of the Old World collection. Node sizes reflect the number of significant migrations emanating from the region observed in the phylogeny, whereas the thickness of lines connecting regions reflects the estimated relative rate between regions. Inferred rates are symmetric and do not indicate directionality
