Comparison of Different Approaches to Prevent Tuberculosis in People Living With HIV.

Data are described as n (%) or median (range), unless otherwise specified. CI, confidence interval. IGRA; interferon-gamma release assay; IQR, interquartile range; pVL, HIV plasma viral load; WHO, World Health Organization.
* pVL/CD4 approach include those with high HIV viral load of > = 100,000 copies/mL and low CD4 cell counts of < 350 cells/μL
**pVL/CD4 approach augmented by IGRA includes those in the pVL/CD4 approach and additionally those with a positive IGRA test; IGRA approach include those with positive IGRA tests only and the W.H.O. approach does no testing and includes all.
†In those with CD4 ≥ 350 cells/μL, the proportion testing IGRA-positive was 72/545 (13.2%), and in those with high HIV plasma viral load ≥ 100,000 copies/mL, 1/14 (7.1%).
