Should we be worried? Retractions in complementary and alternative medicine journals

The objective of this study was to explore the nature of retraction notices associated with complementary and alternative medicine focused journals.

Data related to retractions in complementary and alternative medicine journals were extracted from the Retraction Watch Database for the period 2000-2025.

The analysis found that there were 902 notices associated with 42 complementary and alternative medicine journals. Overall, the percentage of retractions relative to all papers published in the named journals is low (<1%) however a single journal was responsible for 84% of retractions. The majority of these retractions occurred in 2023 as the result of a wider publisher investigation into paper mills and sham peer-review. Similar to other studies, retraction was rarely due to a single cause but reflected a mix of data integrity concerns, peer-review issues, evidence of plagiarism and other issues. The average time between original publication and retraction was 19 months (mode 10 months) with 98% of publications having multiple authors. The main country of origin of authors of retracted works were China, India and South Korea.

Published peer-reviewed literature is used in a range of ways, as the foundation for future studies, incorporated in systematic reviews, clinical decision-making and in training of practitioners and clinicians. While this study has demonstrated that retractions in the complementary and alternative medicine literature is generally at a lower level, any evidence of publication integrity breach is a concern and should be cause for ongoing monitoring.
