Retraction Statement.

The article "Identification of LGR5 and TFF2 as Biomarkers in High-Risk Chronic Atrophic Gastritis: From Multi-Omics Mining to Clinical Validation" [Digestion. 2026; https://doi.org/10.1159/000549887] by Qingqing Zhang, Di Wu, Fengyun Guo, Shengnan Yang, Lijing Bao, Ruiying Zhang and Ping Wang has been retracted by the Publisher and the Editor.Post-publication concerns were raised regarding the integrity of the clinical cohort data reported in the article. The data presented in Table 1 shares the same subgroup size, gender distributions and H. pylori infection rates across all three subgroups to those reported in a previously published article by the same research group [1]. Additionally, the images in Figure 4b and d of this article are published as Figure 2a and b in [1]. The previous publication was not cited in this article.When asked about the similarities between the cohorts, the authors stated that they were two independent cohorts and that the similarities were coincidental. The Editors did not find the authors' explanation sufficient to resolve their concerns, and as a result have lost confidence in the reliability and originality of the reported cohort data.The authors did not respond to our correspondence about the retraction of this article within the timeframe specified.
