a, The phylogenetic placement of the DCCs in the M. abscessus species phylogenetic tree. Several non-DCC clades have been collapsed for clarity; the full tree is presented in Extended Data Fig. 1. b, The proportion of individuals from each location infected with each DCC. All samples from Brazil are from a surgical outbreak caused by a single lineage30. c, Temporal maximum clade credibility phylogenetic tree of each DCC. DCC most recent common ancestor dates are shown as median with 95% HPD in parentheses. Shaded areas show the first period of rapid divergence in each DCC. d, Expansion date distributions for each DCC as calculated from the complete posterior distribution of trees (number of samples from the posterior distribution: DCC1 = 2,255, DCC2 = 2,255, DCC3 = 2,255, DCC4 = 2,699, DCC5 = 2,702, DCC6 = 2,613, DCC7 = 2,703). Boxplot centre lines show median value; upper and lower bounds show the 25th and 75th quantile, respectively; upper and lower whiskers show the largest and smallest values within 1.5 times the interquartile range above the 75th percentile and below the 25th percentile, respectively; and points show samples outside the whisker range.
