RETRACTION: S. Wan , H. Yan , Q.-Y. Sun , J.-Q. Zhu , H.-H. Wang , K.-Y. Qu , and X. Yi , "Effects of GLP-1 Receptor Agonists on Cognitive Function in Patients With Type 2 Diabetes: A Systematic Review and Meta-Analysis Based on Randomized Controlled Trials," Diabetes, Obesity and Metabolism (Early View): https://doi.org/10.1111/dom.70201. The above article, published online on 17 October 2025 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Richard Donnelly; and John Wiley & Sons Ltd. The retraction has been agreed due to concerns raised by third parties and upon the authors' request. It was brought to the journal's attention that the original studies forming the basis of the meta-analysis presented in the article contain inconsistencies that are prone to misinterpretation. As a result, these studies were found not to be directly comparable. Consequently, the conclusions drawn in the article were determined to be affected by these issues, and their reliability was considered compromised. To their credit, the authors have agreed with this determination and requested the retraction of the article. The authors have acted responsibly after concerns were raised and following their own internal investigations of the research.
