Gamma Survival Curves showing the proportion of patients who have yet to start antiretroviral treatment (survival) with increasing duration of tuberculosis treatment (analysis time in months). Data are adjusted for other co-variates shown in Table 1 with the reference group in each plot representing patients with CD4 cell counts in the range 100-199 cells/μL cared for at treatment site 3 in 2005. Data are shown stratified by (a) blood CD4 cell count; (b) calendar year of starting treatment and (c) treatment site.
