Retraction Note to: Radiofrequency ablation versus hepatic resection for breast cancer liver metastasis: a systematic review and meta-analysis

Abstract

The authors have retracted this article (Xiao et al., 2018). After publication, they became aware that a number of studies included in the meta-analysis did not meet the eligibility criteria and that errors were made in classification and statistical analysis. The conclusions presented are therefore unreliable. All authors agree with this retraction.
