E. Treggiari, E. Catania, P. Valenti, K. Boyd, and R. Finotello, "Factors Associated with the Development of Gastrointestinal Adverse Events in Dogs with Multicentric Lymphoma Treated with CHOP or CEOP-Based Protocols: a Multi-Institutional, Retrospective Study," Journal of Small Animal Practice (Early View). https://doi.org/10.1111/jsap.13880. The above article, published online on 04 May 2025 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Marije Risselada; the British Small Animal Veterinary Association; and John Wiley & Sons Ltd. Concerns have been raised about statistical errors in the article. A review by the journal editors has confirmed that the reported odds ratios for DOX vs EPI are incorrect and the related interpretation in the Discussion and Conclusions therefore contain errors. The retraction has been agreed to because the errors in the reported odds ratios fundamentally compromise the Discussion and Conclusions reported in the article. Due to the comprehensive nature of the errors, a correction was not considered possible. The journal editors have determined that the authors may submit a revised version of their article to the journal for potential publication following further review.
