Figure 3 |. Bayesian maximum clade credibility (MCC) tree of PDCoV strains.

The MCC tree was inferred from a subset of 94 full genome strains that displayed sufficient temporal signal for molecular clock calibration. Branch lengths were scalded in time, according to the bar at the bottom, by enforcing a strict molecular clock and using sampling dates to estimate PDCoV evolutionary rate. Circles at internal nodes indicate high posterior probability (PP) support >0.9. The table on the left shows the inferred time of the most recent common ancestor (TMRCA) between Haitian strains and their closest phylogenetic relative, with 95% high posterior density intervals (95%HPD).
