Community State Type dynamics. Swab 1 taken at mean 12.8 weeks of gestation, swab 2 at mean 19.3 weeks of gestation and swab 3 at mean 23.3 weeks of gestation. A) Distribution of community state types (CSTs) at different sampling moments during pregnancy, for all participants, White European participants and non-White European participants. B) On the left bars depicting the distribution of CSTs of swab 1 and 2 of participants that were treated for bacterial vaginosis (BV) and on the right participants that were not treated for BV. BV treatment was given to participants between swab 1 and 2 if Nugent score ≥4 or G. vaginalis was present in cervicovaginal culture in a separate sample. *P < 0.05, **P < 0.01.
