Effects of the ETG vaginal ring on the percentages of CXCR4⁺ and CCR5⁺ cells in peripheral blood and endocervical T cells. Women were treated with the ETG vaginal ring as described. PBMCs and endocervical cells were isolated at enrollment and approximately 3–4 weeks later. The percentages of CXCR4⁺ cells and CCR5⁺ cells in peripheral blood (a) and endocervical CD4⁺ and CD8⁺ T cells (b) were analyzed using flow cytometry. Data were analyzed using Wilcoxon testing and are presented as median and interquartile range (n = 16). BT: before treatment
