RETRACTION: M. El-Sedeek, A.A. Korish, and M.M. Deef, “ Plasma Orexin-A Levels in Postmenopausal Women: Possible Interaction With Estrogen And Correlation With Cardiovascular Risk Status,” BJOG: An International Journal of Obstetrics and Gynaecology 117, no. 4 (2010): 488–492, https://doi.org/10.1111/j.1471-0528.2009.02474.x.

The above article, published online on 08 February 2010 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Aris Papageorghiou; and John Wiley & Sons Ltd. UK. Concerns were raised by a third party regarding the reported calculations and statistical results. The third party was unable to recalculate the mean BMI using the reported weight and height metrics and also noted that the F values in Tables 1 and 2 were unusually large and the p-values reported in these tables do not appear compatible with the reported summary data. An independent expert evaluated the summary data reported in the article and confirmed the incompatibility of the statistical results and found that both the reported and recalculated F values are implausibly large. The authors did not respond when asked for their original data and clarification. As a result, the data and conclusions are considered unreliable, and the article must be retracted.
