PLHIV who had unfavourable TB treatment outcomes were more likely to be older at the time of TB diagnosis (38 vs. 36 years, p = 0.012) and have lower median CD4+ counts at the time of TB diagnosis (74 vs. 123 cells/μL, p < 0.001); they were less likely to gain weight over the course of TB treatment (0 vs. 2 kg, p < 0.001). Here, CD4 is linked to tuberculosis.
