Model compartments and transition rates.

<p>Boxes represent the proportions of the modeled population that are susceptible to infection, latently infected with <i>M. tuberculosis</i>, in active TB disease, under treatment, or cured. Arrows represent the transitions between various states, including up to four sequential phases of treatment. Rates of transition are described in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096389#s2" target="_blank">Methods</a> section and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0096389#pone.0096389.s001" target="_blank">Appendix S1</a>.
