RETRACTED ARTICLE: Ultrasound-guided versus uterine sound-sparing approach during copper intrauterine device insertion: a randomised clinical trial

Abstract

We, the Editor and Publisher of European Journal of Contraception and Reproductive Health Care, have retracted the following article:

Mohammed K. Ali, Asmaa K. Ramadan, Ahmed M. Abu-Elhassan & Ahmed M.A Sobh (2022) Ultrasound-guided versus uterine sound-sparing approach during copper intrauterine device insertion: a randomised clinical trial, The European Journal of Contraception & Reproductive Health Care, 27:1, 3-8, DOI: 10.1080/13625187.2021.1900565

Since publication, significant concerns have been raised about the validity of the statistical analysis and reported results in the article. When approached for an explanation, the authors fully cooperated with the investigation and provided responses to our queries. However, these responses have not sufficiently addressed our concerns. As we cannot confirm the validity of the trial as reported, we are therefore retracting the article. The authors have been informed of this decision.

We have been informed in our decision-making by our editorial policies and COPE guidelines.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
