“…In all, 293 studies were excluded, the main reasons being the inclusion of only singleton pregnancies (37%), not a test accuracy study (27%), and the lack of original data (24%). A total of 21 studies, including 3523 women with twin pregnancies, 18-38 met the inclusion criteria of which 15 (3001 women) provided data for metaanalyses. Sixteen studies (3213 women) provided data on asymptomatic women 18-33 and 5 studies (310 women) on women with symptoms of preterm labor.…”

“…Sixteen studies (3213 women) provided data on asymptomatic women 18-33 and 5 studies (310 women) on women with symptoms of preterm labor. 34-38 One of the included articles 30 was an extended analysis of an initial study 39 from which we extracted data for metaanalyses of CL ≤25 and ≤35 mm at 20-24 weeks of gestation to predict preterm birth <28 weeks of gestation. Six studies 19-21,28,32,37 could not be included in the metaanalyses because the CL cutoff values used, 19-21,32 and outcome measures evaluated 28,37 did not match those of other studies that provided data for metaanalyses.…”

Objective To assess the accuracy of transvaginal sonographic cervical length (CL) in predicting spontaneous preterm birth in women with twin pregnancies. Study design Systematic review and metaanalysis of predictive test accuracy. Results Twenty-one studies (16 in asymptomatic women and 5 in symptomatic women) with a total of 3523 women met the inclusion criteria. Among asymptomatic women, a CL ≤20 mm 20-24 weeks’ gestation was the most accurate in predicting preterm birth <32 and <34 weeks’ gestation (pooled sensitivities, specificities, and positive and negative likelihood ratios of 39% and 29%, 96% and 97%, 10.1 and 9.0, and 0.64 and 0.74, respectively). A CL ≤25 mm 20-24 weeks’ gestation had a pooled positive likelihood ratio of 9.6 to predict preterm birth <28 weeks’ gestation. The predictive accuracy of CL for preterm birth was low in symptomatic women. Conclusion Transvaginal sonographic CL 20-24 weeks’ gestation is a good predictor of spontaneous preterm birth in asymptomatic women with twin pregnancies.

“…Ten studies (67%) were performed in the United States [28, 29, 32, 33, 35–39, 41], and one each in Italy [27], Sweden [30], Brazil [31], United Kingdom [34], and France [40]. The sample size ranged from 29 [28] to 169 [36] in asymptomatic women and from 38 [38] to 87 [41] in symptomatic women.…”

“…Cervicovaginal fetal fibronectin was measured using enzyme-linked immunoabsorbent assay quantitative method (nine studies [28–30, 33, 35–39]), membrane immunoassay qualitative method (three studies [27, 31, 34]), and rapid TLi system qualitative method (one study [41]). Two studies [32, 40] did not report method for measuring fetal fibronectin. All studies considered a cervicovaginal fetal fibronectin concentration of 50 ng/ml or greater as a positive test result.…”

“…In women without symptoms, three studies evaluated cervicovaginal fetal fibronectin tests to predict preterm birth before 32 weeks’ gestation [29, 33, 37], nine evaluated preterm birth before 34 weeks’ gestation [27–31, 34–37], and six evaluated preterm birth before 37 weeks’ gestation [27, 29–32, 37]. In women with symptoms of preterm labor, three studies evaluated preterm birth within 7 days of testing [38, 39, 41], and two each evaluated preterm birth within 14 days of testing [38, 41], and before 34 [40, 41] and 37 [38, 40] weeks’ gestation.…”

Objective To investigate the accuracy of cervicovaginal fetal fibronectin in predicting preterm birth in women carrying multiple pregnancies. Methods Systematic review and meta-analysis of predictive test accuracy. Cohort or cross-sectional studies were identified through searches in databases, reference lists, proceedings, and reviews. Study selection, quality assessment, and data extraction were performed. We constructed summary receiver operating characteristic curves and calculated pooled sensitivities and specificities using a bivariate, random-effects meta-regression model. We also calculated summary likelihood ratios and post-test probabilities of preterm birth. Results Fifteen studies (11 in asymptomatic women and 4 in women with symptoms of preterm labor) involving 1221 women with multiple pregnancies were included. Among asymptomatic women with multiple or twin pregnancies, the pooled sensitivities, specificities, and positive and negative likelihood ratios for predicting preterm birth before 32, 34, and 37 weeks’ gestation ranged from 33% to 45%, 80% to 94%, 2.0 to 5.5, and 0.68 to 0.76, respectively. Among women with twin pregnancies and threatened preterm labor, the test was most accurate in predicting spontaneous preterm birth within 7 days of testing (pooled sensitivity, specificity, and positive and negative likelihood ratios of 85%, 78%, 3.9, and 0.20, respectively). Conclusions Cervicovaginal fetal fibronectin provides moderate to minimal prediction of preterm birth in women with multiple pregnancies. The test is most accurate in predicting spontaneous preterm birth within 7 days of testing in women with twin pregnancies and threatened preterm labor.

Objective To assess the accuracy and determine the optimal threshold of sonographic cervical length (CL) for the prediction of preterm delivery (PTD) (range, 0.653-0.724 vs 0.620-0.682, respectively; P = 0.3). The optimal threshold of CL for any given target sensitivity or specificity was lower in twin than in singleton pregnancies. However, in order to achieve a negative predictive value of 95%, a higher threshold (28-30 mm)
