Table 1. Six pairs of colonisations for whom transmission was reconstructed with a posterior score of at least 0.95 and, for those reconstructed transmissions, a posterior median of at least five tips were in the recipient subgraphs.

Each row gives the posterior median and the limits of the 95% highest posterior density (HPD) interval for the number of reconstructed transmissions between the subjects, in either direction. The posterior median number of tips in the recipient subgraphs, and the nucleotide diversity amongst those tips, are also given. In five cases the inferred direction of transmission is clear, but for C183 and C194 it is not.
