Treatment failure was more frequent among individuals of Brown race\/skin color, those with multidrug-resistant and extensively drug-resistant tuberculosis, and those with multiple previous treatments. Mortality was higher among individuals over 40 years of age, those with multidrug-resistant and extensively drug-resistant tuberculosis, those with alcohol use, and individuals AIDS.
