High expression of KCNQ1OT1 was a poor prognostic factor for CRC patients. a, b The expression level of KCNQ1OT1 in CRC tissues and cells was analyzed by qRT-PCR. c The correlation between KCNQ1OT1 expression and overall survival of CRC patients was analyzed with Kaplan–Meier method and log-rank test. *P < 0.05, vs. control group
