Time-scaled Bayesian MCC tree of the HIV-1 CRFs09/11/13/45_cpx pol gene fragment. Branch color indicates the subtype classification obtained in this study, according to the legend in top left. The external circular segments highlight the position of each specific clade as indicated at the line. Asterisks point to key nodes with a high (> 0.90) PP support. Branch lengths are drawn to scale with the concentric circles indicating years. The tree was automatically rooted under the assumption of a relaxed molecular clock
