A study found that nulliparous women with a short cervix who have intra-amniotic debris are at a higher risk of early preterm birth. The presence of debris was associated with worse outcomes for the babies, likely due to earlier delivery. Women with debris had a longer funnel and a higher body mass index than those without debris.
