To explore the value of an additional ultrasound examination of the cervix at about 17 weeks.<\/jats:p><\/jats:sec>Methods<\/jats:title>Longitudinal prospective study in 800 unselected pregnant women presenting for first\u2010trimester ultrasound assessment by nuchal translucency and serum biochemistry. Cervical length was evaluated transvaginally between 11 weeks and 13 weeks and 6 days (cx1), at 16\u201319 weeks (cx2) and 20\u201324 weeks (cx3). Backward multiple logistic regression analysis with cx3 \u2264 15 mm as the dependent variable was used to identify the predictors of a short cervix at 20\u201324 weeks.<\/jats:p><\/jats:sec>Results<\/jats:title>Cx1 and history of preterm delivery were significant independent contributors of a short cervix at 20\u201324 weeks [area under the curve (AUC 0.808, p<\/jats:italic> < 0.001, Model) 1]. Furthermore, the cx1\/cx2 ratio was a significant independent predictor of a short cervix at 20\u201324 weeks (odds ratio = 58.325 p<\/jats:italic> = 0.012).
