MTB: Mycobacterium tuberculosis; NTM: Nontuberculous mycobacteria

^a Combined result of two tests if the first test failed. Does include participants with one (n = 38) and two (n = 118) Xpert results of MTB detected;

^b Final culture result, which is the MGIT result unless the MGIT culture was contaminated and the LJ culture result was either no growth or MTB+, then the LJ result was taken (n = 86);

^c Final expert panel conclusion, abnormal meaning chest X-ray with any abnormality suggesting active TB disease;

^d Treatment history as reported by the participant in the in-depth interview; ^d Two of these patients were on TB treatment at the time of the survey.
