Comparison of virologic markers by sex. A, Integrated and total DNA measured in isolated CD4 cells were comparable between men and women. B, Low-level viremia measured by single-copy assay was lower in women than in men. C, Multiply spliced human immunodeficiency virus (HIV) RNA was lower in women. D, There was no statistically significant difference in the level of unspliced HIV RNA. For all values, median and interquartile range are shown; statistical comparisons with negative binomial regression. Abbreviations: CA-HIV, cell-associated-HIV; HIV, human immunodeficiency virus; msHIV, multiply spliced human immunodeficiency virus; usHIV, unspliced human immunodeficiency virus.
