CircMMP11 overexpression in NSCLC predicted poor survival. CircMMP11 expression in paired cancer and non-cancer tissues from the 66 NSCLC patients was analyzed by RT-qPCRs. Differential gene expression in paired tissue samples was presented by heatmaps plotted using Heml 1.0 software (A). The 66 patients were divided into high and low circMMP11 level groups (cutoff value = medium expression level in cancer tissues), and the survival curves were plotted and compared by log-rank test (B)
