Audit of 2.5 million biomedical papers reveals surge in fake citations
 

A recent Nature news report highlighted findings from an audit of 2.5 million biomedical science papers that identified nearly 3,000 papers containing fabricated or unverifiable references. The analysis, which included 97 million citations, found that the rate of fake citations has increased sharply since 2023.

Researchers involved in the study warn that fabricated references could undermine trust in scientific literature and potentially affect clinical guidelines if unreliable citations continue to propagate through the biomedical literature. The report notes concerns that generative AI tools may be contributing to the rise in fabricated references, although the exact causes remain unclear.

These findings have led to renewed calls for publishers and journals to adopt automated reference-checking systems and strengthen editorial screening processes before and during peer review.
