The Publisher and Editor are issuing an Expression of Concern on the article titled “The Effect of Vitamin E on Hot Flashes in Menopausal Women” [Gynecol Obstet Invest 2007;64:204–207; DOI: 10.1159/000106491] by S. Ziaei, A. Kazemnejad, and M. Zareai.
After publication of this article, concerns were raised regarding the accuracy of the demographic information of participants, the choice of statistical test used in Table 3 and the paucity of detail provided about the study location, recruitment method, and period of recruitment. The authors did not respond to our correspondence within the given timeframe and the matter has been raised to the corresponding author’s institution. Readers should thus interpret the data presented in the article with caution. Appropriate editorial action will be taken once the investigation is concluded.
