Changes in median human immunodeficiency virus (HIV) viral load, CD4+, and CD8+ T cell counts among participants receiving tuberculosis treatment alone (A,C) and combined HIV-tuberculosis treatment (B,D). Median values ± interquartile range are shown (A,B). Boxes indicate the interquartile ranges, the horizontal lines transecting the boxes indicate the medians, and the whiskers indicate the highest and lowest values (C,D). Nonparametric rank tests were performed to compare median changes in viral load, CD4+, and CD8+ T cell counts within each treatment arm from baseline to months 3, 6, 9, and 12. Significant P values are indicated. TB, tuberculosis.
