Statement of Retraction
We, the Editors and Publisher of The Journal of Maternal-Fetal & Neonatal Medicine, have retracted the following article:
Alaa M. Ismail, Ahmed M. Abbas, Mohammed K. Ali & Ahmed F. Amin; Peri-conceptional progesterone treatment in women with unexplained recurrent miscarriage: a randomized double-blind placebo-controlled trial, The Journal of Maternal-Fetal & Neonatal Medicine, http://10.1080/14767058.2017.1286315
While this article was peer-reviewed and accepted according to the Journal’s policy concerns were subsequently raised regarding the accuracy and reliability of the data. The Editors-in-Chief were made aware of previous versions of the article which showed significant changes to the underlying data. After an investigation the authors of the paper were contacted but were unable to provide the original data to verify their results. The authors have been informed about the retraction.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.
The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
