  1. Characteristics of HIV-TB co-infected patients grouped base on whether they have died or are alive at the end of the follow-up period. Log-rank test was used to calculate p-values for categorical variables and Wald test (Cox model) for continuous variables. Hazard ratios and their 95% confidence intervals were calculated using Cox model. Hazard ratios for age and CD4 at time of TB diagnosis are per unit increase
