Expression of Concern

Expression of concern: Meta-analysis assessment of GP210 and SP100 for the diagnosis of primary biliary cirrhosis

  • The PLOS One Editors

The PLOS One Editors issue this Expression of Concern for this article [1] because of concerns identified about the peer review process. Readers are advised to interpret the article [1] with caution.

The PLOS One Editors also wish to make readers aware that there is substantial overlap between the content of this article and that of another article subsequently published in the Chinese Journal of Hepatology [2].

An internal editorial assessment has established that this constitutes redundant publication. As the first of the two publications, the PLOS One article stands. The Chinese Journal of Hepatology has been informed.
