RR: relative risk; CI: confidence interval; TB: tuberculosis; ART: antiretroviral therapy. Unfavourable outcomes include death, loss to follow-up, and “outcome not evaluated.” †Adjusted RR is based on the multivariable model (log-binomial regression), and all exposure variables were included in the model. ‡ values are from multivariable analysis, and values < 0.05 are highlighted in bold.
