Expression of Concern: Comparison of 18F-FDG PET/CT and DWI for detection of mediastinal nodal metastasis in non-small cell lung cancer: A meta-analysis

The PLOS ONE Editors
PMCID: PMC10866507  PMID: 38354184

After this article was published, similarities were noted between this article [1, 2] and submissions by other research groups which call into question the validity and provenance of the reported results.

In response to queries about these concerns, the first author provided the underlying data in S1-S3 Files.

The authors commented on aspects of how data were collected and analyzed for this study, but overall their responses did not fully resolve the concerns.

The PLOS ONE Editors issue this Expression of Concern to notify readers of the unresolved concerns discussed above, and to provide the data received from the authors.
