摘要

BioMed Research International has retracted the article titled “Correlation of CCNA1 Promoter Methylation with Malignant Tumors: A Meta-Analysis Introduction” [1]. This article is one of a series of very similar meta-analyses written by different authors that were published in 2014 and 2015, characterized by the use of particular phrases [2]. The articles have the same structure, with the figures in the same order. The appearance of the figures and parts of the text are also similar.
