Extended Data Table 5. Estimated migration rates between lymph nodes and blood using Bayesian inference under the structured coalescence.

Migration rates (in fraction of emigrants per month) were estimated in the Gag region of HIV-1 for the three study subjects using Bayesian inference under the structured coalescence model, assuming a constant population size and a strict molecular clock. Migration rates from lymph node to blood and vice versa are shown with their standard error of the mean (SEM) after running at least 50 million MCMC steps and reaching high values of estimated sample sizes (ESS) for all parameters.
