After this article [1] was published, the following concerns were noted:
- The articles cited as References 4, 5, 10, 17, and 21 appear to be irrelevant to this article [1].
- The articles cited as References 3, 4, and 45 were retracted before [1] was published
We regret that the issues were not identified prior to the article’s publication.
In light of these concerns, the PLOS One Editors issue this Expression of Concern. Readers are advised to interpret the article [1] with caution.
