Phenotypic drug susceptibility profile and genetic sequence analysis of all cavities of each patient.

aLUL, Left upper lobe; LLL, left lower lobe, RUL, right upper lobe; RLL, right lower lobe.bS: Streptomycin, H:Isoniazid, R:Rifampicin, E:Ethambutol, Km:Kanamycin, Eto:Ethionamide, PAS:para-aminosalicylic acid, Ofx:Ofloxocin, Mfx:Moxifloxacin, Am:Amikacin, Cfz:Clofaziamine, Cm:Capreomycin, Z:Pyrazinamide.cCavity isolates showing variable drug susceptibility profiles were analyzed by in-house RLBH (except for Ethambutol, PAS, Pyrazinamide, wherein phenotypic DST were repeated to confirm the variable drug susceptibility profile).dwt – wild type.
