Retraction: Diagnostic value of transvaginal ultrasound combined with serum CA125 and HE4 in differentiating benign and malignant ovarian tumors

Post-publication, an investigation initiated by editorial team identified that a large proportion of the references cited in the article [1] have low relevance or no direct connection to the study’s methods, results, or discussion. This extensive use of irrelevant citations undermines the academic rigor and reliability of the published work. The article is therefore retracted. The authors did not respond with the retraction.

The journal apologizes to its readers for any inconvenience caused.
