Study findings showed there is a more likelihood to have a treatment success in HIV-TB patients (88.6%) than in the TB patients (82.3%). More patients had a treatment success from 6 months to 8 months than before 6 months and after 8 months. HIV does not significantly influence TB treatment outcomes in HIV-TB and non-HIV TB patients.
