Retraction Note
The Editor-in-Chief has retracted this article [1] because of an error in the meta analysis. Re-examination of the data has showed that there is only one published randomized controlled trial comparing Superion with XStop. Due to a misunderstanding of the published clinical data, the conclusions drawn in the article are incorrect. Author Xing Yu approved this retraction, none of the other authors replied to correspondence from the publisher about this retraction.
