CD40LG and syphilis: By multivariable logistic regression analysis, history of STIs predicted HSV-2 IgM seropositivity (aOR: 3.70, 95%CI: 1.43–9.62) while parity (aOR: 1.23, 95%CI: 1.04–1.46) predicted HBV infection and syphilis positive results (aOR: 8.63, 95%CI: 2.81–26.45) predicted HIV infection.
