RETRACTED: The preoperative platelet–lymphocyte ratio versus neutrophil–lymphocyte ratio: which is better as a prognostic factor in oral squamous cell carcinoma?

The following article has been retracted at the request of the Editor and Publisher: Chen S, Guo J, Feng C, Ke Z, Chen L, Pan Y. The preoperative platelet–lymphocyte ratio versus neutrophil–lymphocyte ratio: which is better as a prognostic factor in oral squamous cell carcinoma? Therapeutic Advances in Medical Oncology. May 2016; 160-167 (doi:10.1177/1758834016638019).

The journal editor was notified about concerns regarding the validity and legitimacy of the article’s data and statistical methodology. The article was re-evaluated by a Senior Editor, two external biostatisticians, and one external head/neck medical oncologist who determined that the statistical analysis employed was fundamentally flawed. The authors did not supply the underlying raw data when requested.

As the conclusions of the article cannot be supported by the findings, the Therapeutic Advances in Medical Oncology editor has retracted the article.
