Abstract

Significance: Premature birth (PTB) is a major global public health burden. Previous studies have suggested an association between altered vaginal microbiota composition and PTB, although findings across studies have been inconsistent. To address these inconsistencies, improve upon our previous signature, and better understand the vaginal microbiota’s role in PTB, we conducted a case-control study in two cohorts of pregnant women: one predominantly Caucasian at low risk of PTB, the second predominantly African American at high risk. With the results, we were able to replicate our signature in the first cohort and refine our signature of PTB for both cohorts. Our findings elucidate the ecology of the vaginal microbiota and advance our ability to predict and understand the causes of PTB.

  • Women who went on to experience spontaneous PTB were less likely to exhibit a vaginal microbiota dominated by Lactobacillus crispatus.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
