Abbreviations: SIL, squamous intraepithelial lesions; L/HSIL, low-grade/high-grade squamous intraepithelial lesions.
Bold type indicates statistical significance (p < 0.05) differences in the prevalence of SIL by HPVs overall and stratified by HIV using Pearson's Chi-Square and Fisher's exact tests.
