Compared to those HIV-infected individuals with CD4+ T-cell counts < 200 cells/μl, those with CD4+ T-cell counts ≥ 200 cells/μl were more likely to present with cavitations, either in the TB group (41.67 vs 13.80%) or the non-TB group (5.00% vs 4.60%). This evidence concerns the gene CD4 and tuberculosis.
