RETRACTION of “Correlation analysis between an IL-6 genetic polymorphism and non-small cell lung cancer prognosis”, by Zhao K, Xu J, Tian H published in Genetics and Molecular Research 15 (1): 15017021 (2016) DOI: 10.4238/gmr.15017021
Zhao Kai, first author wishes to retract the following article:
According to the author, the reasons for the retraction are as follows:
- All patients enrolled in the study received surgical resection and lymph node dissection. So the patients’ information was incorrect. Then, the corresponding information and data need to be collected again and reanalyzed.
- The P value for Figure 1 was calculated by the log-rank test. Since the data need to be reanalyzed, the 95% confidence intervals for the average survival times also need to be recalculated.
