Fig. 1. Elevated lncRNA H19 was expressed in CRC tissues and cell lines.

a Quantitative RT-PCR (qRT-PCR) analysis of H19 expression in CRC tissues and pair-matched adjacent normal samples (Non-recurrence group n = 76, and Recurrence group n = 34). b Kaplan–Meier analyses of the associations between H19 expression level and recurrence free survival (RFS) of patients with CRC (the log-rank test was used to calculate P-values). P = 0.0071 vs. low H19 expression group. c Univariate analysis was performed in previous cohort. The bars correspond to 95% confidence intervals. d Multivariate analysis was performed in previous cohort. The bars correspond to 95% confidence intervals
