Figure 1.

Hierarchical clustering of Wnt antagonist DNA methylation status and EGFR genotype in 155 patients received EGFR-TKI therapy. Red represents methylated gene or mutated EGFR, while blue represents unmethylated gene or wild-type EGFR, The figure of hierarchical clustering showed that the epigenotype of Wnt antagonist genes had similar patterns, which were different from the genotype of EGFR.
