CTBP1-AS2 was downregulated in EC and correlated with poor survival. Expression levels of CTBP1-AS2 in both EC and non-tumor tissues from the 62 patients were measured by performing RT-qPCR. All PCR reactions were expressed as mean values and were compared by paired t test (a).***,p < 0.001. The 62 patients were grouped into high and low CTBP1-AS2 level groups (31 patients for each group). Survival curves were plotted using GraphPad Prism 6 software. Comparison of survival curves was performed using log-rank test (b)
