X. Wang, C. Zhang, Xia Li, H. Qi, Q. Liu, and J. Lei, "Safety and Efficacy of Titrated Oral Misoprostol Solution Versus Vaginal Dinoprostone for Induction of Labor: A Single-Center Randomized Control Trial," International Journal of Gynecology & Obstetrics 154, no. 3 (2021): 436-443. https://doi.org/10.1002/ijgo.13546. The above article, published online on 17 December 2020, in Wiley Online Library (wileyonlinelibrary.com), and has been retracted by agreement between the journal Editor-in-Chief, Professor Michael Geary; the International Federation of Gynecology and Obstetrics; and John Wiley and Sons Ltd. A third party raised concerns regarding errors in the reported data and statistics of the article. An external statistician reviewed the data and was not able to reproduce the listed results for the Bishop score, the post-term pregnancy variable, the gestational hypertension variable, the not using insulin variable, the vaginal delivery variable, and the failed induction variable. In addition, the journal detected numerical errors in Table 4, with contradictions between frequencies and reported percentages. The authors did not respond to multiple requests for an explanation and the original data. The editors have determined that the large number of errors identified and lack of original data provided fundamentally compromise the results presented, which necessitates retraction. The authors did not respond to our notice regarding the retraction.
