Figure 5

T-SPOT.TB positive rates in patients with active TB by different durations of TB treatment and CD4+ T cell counts. The black column represents the T-SPOT.TB positive rate of patients with CD4+ T cells <200/μl, and the gray column represents that of patients with CD4+ T cells ≥200/μl. There are decreasing tendency of T-SPOT.TB positive rate with increasing treatment duration in both CD4+ T cells ≥200/μl and CD4+ T cells <200/μl subgroups. But P > 0.05 between subgroups of different treatment durations and subgroups of different CD4+ T cell counts.
