^aSerum, plasma, cells, and CVL samples were stored for every visit from 1994 to present, provided sufficient amounts were obtained (priority given to protocol testing); urine collected at each visit between 1994 and 1998; oral fungal cultures collected at baseline visit.

^bPBMC, cryopreserved peripheral blood mononuclear cells from cell preparation tubes; CVL, cervicovaginal lavage fluid.
