Association of smear-negative and extrapulmonary TB patient samples with basic demographic and epidemiologic variables.

ART = antiretroviral therapy. TB = tuberculosis.A total of 81 deaths and 126 unfavorable outcomes were recorded among the 605 smear negative TB patients, compared to 69 deaths and 120 unfavorable outcomes among the sample of 485 extrapulmonary individuals. The log rank test for equality of survivor functions shows that the data are consistent with no difference in survivor functions for mortality or unfavorable treatment outcomes between the smear-negative and extrapulmonary TB patient samples (p = 0.908 and 0.451, respectively).
