〈 i 〉 Objectives: 〈 /i 〉 To investigate if a cervical length (CL) cutoff of 15 mm is relevant to use in women with threatened preterm labor. 〈 i 〉 Methods: 〈 /i 〉 From 2006 to 2009, 146 women with singleton pregnancies were admitted with threatened preterm labor between 23 and 33+6 weeks of gestation at Copenhagen University Hospital. Transvaginal sonographic measurement of CL was carried out on admission. Outcome measures were spontaneous delivery within 48 h, within 7 days and delivery before 34 weeks according to a CL cutoff of 15 mm. 〈 i 〉 Results: 〈 /i 〉 CL was 〈 15 mm in 36 women (24.7%) and ≧15 mm in 110 women (75.3%). Spontaneous delivery occurred within 48 h or 7 days of presentation and before 34 weeks in 25, 38.9 and 50.0% of women with CL 〈 15 mm and 3.6, 9.1 and 11.8% of women with CL ≧15 mm, respectively. The 15-mm CL cutoff had a sensitivity, false positive rate and negative predictive value for delivery within 48 h of 69.0, 20.3 and 96.4%, and within 7 days of 58.3, 18.1 and 90.9%. Women with CL 〈 15 mm had odds of delivery within 7 days of 6.4 (95% CI 2.5–16.2). 〈 i 〉 Conclusion: 〈 /i 〉 Although a 15-mm CL defines a group of women at high risk of spontaneous preterm delivery, 10 out of 110 women (9.1%) with a CL ≧15 mm deliver within 7 days.
