RETRACTION: Association of biochemical markers with the severity of pre-eclampsia.

Abstract

Retraction: A. M. Maged, G. Aid, N. Bassiouny, D. S. Eldin, S. Dahab, and N K. Ghamry, "Association of Biochemical Markers With the Severity of Pre-Eclampsia," International Journal of Gynecology & Obstetrics 136, no. 2 (2017): 138-144, https://doi.org/10.1002/ijgo.12029. The above article, published online on 16 November 2016 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Michael Geary; the International Federation of Gynecology and Obstetrics; and John Wiley & Sons Ltd. The retraction has been agreed upon following an investigation into concerns raised by a third party regarding improbable values of free categorical variables in Table 1; the statistical significance in Table 1, 2, 3 and 5, where the P-values could not be reproduced using the information presented in the article; and inconsistent information on the number of stillbirth and stillborn neonates in Table 5. The authors were informed about the concerns, but they did not wish to cooperate with the investigation and were not able to provide the raw data as the study was conducted more than 5 years ago and the original data was no longer retained according to institutional policies. The authors' institute was also contacted, but they remained unresponsive. In the absence of a satisfactory explanation or supporting raw data, the editors have determined that the data for this study cannot be considered reliable and decided to retract the article.
