“…After reviewing the full-text of the selected six articles, we excluded two further articles because it was not possible to extract the numbers of TP, FP, FN, and TN for an established score threshold [18,23]. Finally, four studies were included for meta-analysis [19][20][21][22].…”

“…The study of Swiatkowska-Freund and Price, including 29 patients, found a significant correlation between elastographic features of the internal os and labor induction success. On the contrary, both the studies of Pereira et al and Sonnier et al, including respectively a total of 99 and 36 women, found no significant contribution from elastography for prediction of vaginal delivery and induction-to-delivery interval compared to nulliparity and cervical length [23] and for prediction of vaginal delivery within 24 h [24]. Nonetheless, the study by Sonnier et al could not be evaluated in details as only the abstract was written in English language, and was therefore excluded from the meta-analysis [24].…”

“…Nonetheless, the study by Sonnier et al could not be evaluated in details as only the abstract was written in English language, and was therefore excluded from the meta-analysis [24]. Furthermore, Pereira et al found a significant correlation between elastographic score and induction-to-delivery interval in univariate analysis [23]. However, they found this correlation not significant in multivariate analysis but they also stated that as far as there were significant associations between cervical length and the elastographic score, it was possible that studies in larger and more homogeneous populations may demonstrate significant contributions from the elastographic score in the prediction of labor outcome [23].…”

“…This new ultrasound tool aims to allow an objective evaluation of the cervical stiffness, thus potentially replacing the current subjective evaluation by digital palpation. Several approaches have been proposed with encouraging preliminary results, and now clinical studies evaluating the effectiveness of cervical elastography in predicting preterm delivery [12][13][14][15][16] and a successful labor induction are rapidly increasing [8,[17][18][19][20][21][22][23][24]. We performed this meta-analysis to assess the accuracy of cervix elastography in predicting labor induction success.…”

Aim: To determine the accuracy of cervical elastography in predicting labor induction success. Materials and methods: A systematic search, review, and meta-analysis of observational studies published in English language between January 2000 and October 2014 was performed. It included studies considering cervix sonoelastography as the index test and successful labor or vaginal delivery as the reference standard. As cervix length and Bishop score were considered comparator tests, the quality of the included studies was assessed using quality assessment tool for diagnostic accuracy studies (QUADAS) tool. Results: A total of four studies assessing 323 women before medical induction of labor were included. Cervical elastography, cervical length, and Bishop score showed a diagnostic odds ratio (DOR) with 95% confidence interval (CI) for successful labor prediction of 3.50 (1.93-6.35), 3.35 (1.94-5.77), and 1.45 (0.33-6.41), respectively. In addition, cervical elastography, cervical length, and Bishop score showed a DOR with 95% CI for successful vaginal delivery prediction of 5. 24 (3.23-8.50), 4.94 (2.72-8.98), and 4.62 (0.69-30.94), respectively. Considering the summary of receiver operating characteristic curves we show that cervical elastography or length are similarly reliable, and both are more reliable to predict successful labor than the Bishop score. Two studies were excluded because it was not possible to retrieve data for the meta-analysis. Among the excluded studies, one found no significant contribution from elastography for prediction of successful labor induction. Conclusions: Even though there is a limited number of studies included and the heterogeneity of the methods used, cervical elastography seems to be a promising tool for predicting successful labor induction and vaginal delivery in women treated by medical induction of labor.

Objectives The aim of this study was to determine whether cervical elastographic parameters in addition to cervical length (CL) during the 3 trimesters of pregnancy would be predictive of spontaneous preterm birth (sPTB) among low‐risk women. Methods This work was a prospective nested case‐control study evaluating cervical elastographic parameters and CL in low‐risk women during the 3 trimesters of pregnancy. A binary logistic regression analysis was used to calculate significant covariates for prediction of sPTB. The area under the curve of the prediction model was calculated by using a receiver operating characteristic curve. Results There were 286 women (26 cases and 260 controls) included in the analysis. The parameters of cervical elasticity became softened and heterogeneous during the 3 trimesters of pregnancy in both women with and without sPTB. The differences in the mean strain value at the internal os of the cervix (IOS), ratio (strain ratio of the internal os to the external os) during the second trimester and the IOS during the third trimester between the groups had statistical significance (P < .01; P = .01; P < .01, respectively). The CL had no association with sPTB during the 3 trimesters. The IOS during the second trimester was a better predictor of sPTB, with an area under the curve of 0.730, and sensitivity was 72.73%. Conclusions We observed multiple elastographic parameters and demonstrated the physiologic changes in the cervix during the 3 trimesters of pregnancy. Furthermore, we found that the IOS during the second trimester can be helpful in predicting sPTB. However, the CL had no association with sPTB during the 3 trimesters of pregnancy.
