RETRACTED ARTICLE: The effects of coenzyme Q10 supplementation on gene expression related to insulin, lipid and inflammation in patients with polycystic ovary syndrome

Statement of Retraction

We, the Editor and Publisher of the Gynecological Endocrinology, have retracted the following article:

Elham Rahmani, Mehri Jamilian, Mansooreh Samimi, Maryam Zarezade Mehrizi, Esmat Aghadavod, Elmira Akbari, Omid Reza Tamtaji & Zatollah Asemi (2018), The effects of coenzyme Q10 supplementation on gene expression related to insulin, lipid and inflammation in patients with polycystic ovary syndrome, Gynecological Endocrinology, 34:3, 217-222, DOI: 10.1080/09513590.2017.1381680

Following publication, significant concerns were raised by a third party [1] about the integrity of the data and the reported findings in the article.

When approached for an explanation, the authors and their institution have been cooperative in providing some original data and documents. In order to verify the reported findings, the article and the original data provided by the authors were sent for review by an external statistical reviewer.

Both the journal editorial team and the external statistical reviewer were unable to confirm the integrity of the trial design and the main outcome of the external review was that the article's results and conclusions are unreliable and highly open to bias. Therefore, as the editorial team no longer have confidence in the reported conclusions the decision has been made to retract the article.

The authors listed in the publication have been informed. The authors do not agree with the retraction.

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

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as 'Retracted'.
