Retraction: A. M. Maged, H. Rashwan, S. AbdelAziz, W. Ramadan, W. A. I. Mostafa, A. A. Metwally, M. Katta, "Randomized controlled trial of the effect of endometrial injury on implantation and clinical pregnancy rates during the first ICSI cycle," International Journal of Gynecology & Obstetrics 140, no. 2 (2018): 211-216, https://doi.org/10.1002/ijgo.12355. The above article, published online on 19 October 2017 in Wiley Online Library (wileyonlinelibrary.com) has been retracted by agreement between the journal's Editor-in-Chief, Michael Geary, International Federation of Gynecology and Obstetrics and John Wiley & Sons Ltd. The retraction has been agreed following an investigation based on concerns raised by a third party. Significant inconsistencies were found between the P-values calculated in Table 3 and data provided within the paper. The original data was no longer available as this is archived after a period of five years according to institutional policies. Thus, the inconsistencies in the paper could not be resolved. Accordingly, the editors consider the conclusions of this manuscript insufficiently supported. The authors disagree with the retraction.
