RETRACTED: The use of oral nomegestrol acetate/estradiol in rapid and random start preparation of endometrium before office hysteroscopic polypectomies: A multicenter, prospective, randomized controlled trial

Abstract

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). The Editor-in-Chief has decided to retract this article. A reader alerted the Editors to similarities between this trial and a different trial reported in the journal Climacteric : Etrusco A, D'Amato A, Agrifoglio V, Chiantera V, Russo G, D'Augè TG, Monti M, Riemma G, Laganà AS, Giannini A. Rapid and random-start endometrial preparation before outpatient hysteroscopic polypectomy in patients of perimenopausal age. Climacteric. 2024 Dec;27(6):561-567. doi: 10.1080/13697137.2024.2404574. Epub 2024 Sep 27. PMID: 39329272. The two studies recruited over the same time period in the same centre, and there is evidence of data copying between them. The corresponding author cooperated with the investigation by supplying original data from both trials. Both sets of data showed evidence of fabrication. The EJOG Editors are therefore retracting this paper. The authors disagree with the retraction and dispute the grounds for it. The Editor of Climacteric has been informed.
