76 versus 0.65, difference in AUC 0.11, 95%CI 0.01-0.23). At C×2, the shortest endocervical length of ≤25mm (prevalence 4.4%) predicted sPTB at 33weeks of gestation with sensitivity 38.5% (10/26), specificity 95.8% (5998/6262), PPV 3.6% (10/274), NPV 99.7% (5988/6014), LR+ 9.1, LR- 0.64, FP/TP 26 and NNS 629. Second-trimester sonographic cervical length can identify women at high risk of sPTB. In a population of mainly white women with a low prevalence of sPTB its diagnostic performance is at best moderate. Cervical leng
