  • *Sneathia sanguinegens, Sneathia amnionii, Atopobium vaginae, and BVAB1. Comparison group consists of women who tested negative for all four bacteria. In model of ‘all positive’, women testing positive for some but not all bacteria are excluded.

  • †All models are adjusted for age and race. Infertility model additionally adjusted for self-reported infertility at baseline.
