Combined assessment of drug-resistant minority variants and mixed M. tuberculosis strain populations detected in specimens with majority drug-resistant or drug-susceptible strains. DR: drug resistant (majority variants resistant to any first-line TB drugs); DS: drug susceptible (majority variants susceptible to all first-line TB drugs); DR-MVs: drug-resistant minority variants; MDR: multidrug resistant; Mixed: mixed strain population; NSW: New South Wales; PCR: M. tuberculosis-specific polymerase chain reaction; Single: single strain population; TB: tuberculosis. *Group 1 (“Assoc W R”) drug-resistant variants, as in 2021 WHO Catalogue (23, 24). **Group 2 (“Assoc W R - Interim”) drug-resistant variants, as in 2021 WHO Catalogue (23, 24).
