RETRACTION: Role of First-Trimester Three-Dimensional (3D) Power Doppler of Placental Blood Flow And 3D Placental Volume in Early Prediction of Pre-Eclampsia.

Abdallah, A., Khairy, M., Tawfik, M., Mohamed, S., Abdel-Rasheed, M., Salem, S., and Khalifa, E., "Role of First-Trimester Three-Dimensional (3D) Power Doppler of Placental Blood Flow And 3D Placental Volume in Early Prediction of Pre-Eclampsia," International Journal of Gynecology & Obstetrics 153, no. 3 (2021): 466-473, https://doi.org/10.1002/ijgo.13572. The above article, published online on 23 December 2020 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Michael Geary; and John Wiley & Sons Ltd. UK. Concerns were raised by a third party regarding the reported results, particularly the mean gestational age at delivery of the normotensive group, which is stated in the article as 36.67 weeks. In light of these concerns, the authors were asked to provide their raw data. The authors did not provide the requested study data but responded that rounding accounted for the short duration of pregnancy, as well as cultural healthcare practices in the study region. However, the editorial team and publisher did not feel that this was an adequate response to the concerns. Lacking the study data for further analysis and the inconsistencies present in several places in the article, including the odds ratios in Tables 1 and 3, the editors consider the data and conclusions to be unreliable. Therefore, the article must be retracted. When informed of the decision to retract, M. Abdel-Rasheed, on behalf of the authors, disagreed with our decision to retract.
