  • Bold values are statistically significant.

  • *Women with an unassessable MG result (n=15) and/or Chlamydia trachomatis were excluded from the analysis (n=100; includes eight women coinfected with MG and C. trachomatis).

  • †All analyses were adjusted for number of male sexual partners, vulvovaginal candidiasis, Neisseria gonorrhoeae and concurrent BV.

  • ‡P value calculated using logistic regression.

  • §Data missing for up to 3% of participants.

  • ¶STI in the past 6 months referred to bacterial STI only, however some women may have misinterpreted this question and answered with regard to warts or other non-bacterial STIs, and therefore this should be interpreted with caution.

  • **Abnormal vaginal odour refers to any self-reported odour, not specifically a fishy odour.

  • BV, bacterial vaginosis; n, number.
