Data were abstracted from treatment files and unit DRTB registers. Monthly sputum cultures were performed using the Lowenstein\u2013Jensen solid medium.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We included 664 people with DRTB and a positive baseline culture, of whom 353 (53.4%) also had HIV. Among those living with HIV, 225 (63.7%) were male and 331 (94.3%) were on antiretroviral therapy. The median month of culture conversion was 2 (interquartile range [IQR] 1\u20133). ECC was observed among 226 people living with HIV (64.0%; 95% confidence interval [CI] 58.9\u201368.9). A DRTB treatment regimen of six or more drugs was associated with ECC among people living with HIV (adjusted odds ratio [aOR]\u00a0\u00a03.82; 95% CI 1.06\u201313.82; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.041). Cure and overall treatment success was observed among 232 (65.7%) and 269 (76.2%) people living with HIV, respectively. However, ECC was not associated with cure (crude odds ratio [OR]\u00a0\u00a00.97; 95% CI 0.61\u20131.54; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.901), death (OR\u00a01.12; 95% CI 0.61\u20132.29; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.610), or overall treatment success (OR\u00a01.29; 95% CI 0.78\u20132.13; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.326).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The majority of people living with HIV and DRTB achieve ECC. However, ECC does not predict cure, death, or treatment success. Moreover, it may require six or more drugs to achieve ECC. ECC is not an excellent indicator of the effectiveness of DRTB regimens among people living with
