Retraction Note: Vaginal progesterone for prevention of preterm labor in asymptomatic twin pregnancies with sonographic short cervix: a randomized clinical trial of efficacy and safety

Abstract

The Editor-in-Chief has retracted this article. Contrary to the statement in the article, the authors did not obtain approval from a research ethics committee before conducting this interventional randomized control trial and therefore this study is in breach of the Declaration of Helsinki [1] and the editorial policy of the Journal. Concerns about the data reported in the article are under investigation by the University of Mansoura. Waleed El-Refaie stated on behalf of all co-authors that they do not agree with this retraction.
