Associations between cellular alloimmune responses and sexual exposure among ESN FSWs. (a) Association between allostimulated CD69 expression on memory CD4⁺ T-cells and the duration of commercial sex work among ESN FSWs. (b) Association between allostimulated MIP-1β secretion and the consistency in using condoms with regular partners. Allostimulated CD69 expression was tested with linear regression adjusting for age (variable normally distributed). Allostimulated MIP-1β secretion was tested with Mann–Whitney U-tests (variable not normally distributed). P₁, comparison between FBDs and all ESN FSWs; P₂, comparison within ESN subgroups.
