Figure 3. Sensitivity analysis showing Cox proportional hazards model for the combined outcome of death or LTFU at 12 months based on TB status and stratified by baseline CD4 count among HIV-infected adults in Durban, South Africa.

Figure 3

The three TB groups: 1) newly-diagnosed with TB by sputum culture, 2) already taking TB treatment for known/presumed active disease prior to enrollment, and 3) TB free, meaning a negative enrollment sputum culture and not on TB treatment, are further stratified based on CD4 count ≥100/μl and CD4 <100/μl. Analysis is adjusted for smoking status, age, opportunistic infection history, and gender. Vertical lines represent 95% CI around hazard ratios.
