The authors regret that the function to calculate growth rate and results of number of clusters of RR strains were incorrect. Please see correction below:
1. In the method section, "phylogeny and population dynamics", the function used to calculate the growth rate should be as follows. This is a clerical error the results are unaffected.
2. In the results section, "Transmission and positive selection of MDR-TB strains", this sentence: "six clusters including 7 (19.0%) RR strains had recently developed RR related mutations from rifampicin susceptible (RS) strains;" should be "four clusters including 6 (16.2%) RR strains had recently developed RR related mutations from rifampicin susceptible (RS) strains". These clusters / strains were correctly reported in Fig. 4; the four clusters which contain ten strains six of which are RR are:
CN2348(R), CN1124(R), CN2206(R), ancestor(S)
