Retraction Note: J Ovarian Res 13, 3 (2020)
The Editors-in-Chief has retracted this article [1] due to lack of evidence that the study has received ethics approval. After publication it has come to the Editor’s attention that in the body of the article the authors state that their study was approved by the Ethics Committee at the First Hospital of Lanzhou University. However, in the Ethics declarations section, the authors state that their study was approved by the Ethics Committee of the Maternity and Child Care Center of Liuzhou. The authors have not provided documentation of approval from an ethics committee for this study. Yongxiu Yang and Qing-an-zi-Wang agree with this retraction. Xioalei Liang have not responded to any correspondence regarding this retraction.
