Cervical length was measured during standard anomaly scan and a second measurement was performed if the cervical length was 30\u00a0mm of shorter. Logistic regression and Cox proportional hazards modeling were used to evaluate associations between cervical length measurements and spontaneous preterm delivery before 37\u00a0weeks of pregnancy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Cervical length measurements from 12\u00a0358 patients were included; 221 (1.8%) had an initial cervical length measurement of 30\u00a0mm or shorter.
