Objective: To evaluate whether longitudinal transvaginal sonography (TVS) in a standing position improves the prediction of spontaneous preterm birth (SPB). Methods: For upright and recumbent posture, the inter- and intra-observer agreement of cervical length (CL) was calculated. In 363 pregnancies at risk for SPB, we determined CL and funnel width (FW), differences between positions and longitudinal measurements from 15 weeks to term. Multivariate logistic regression, ROC analysis and contingency tables were performed in singleton and twin pregnancies. Results: The inter-class correlation coefficient was 0.952…
