Figure 2

Association of GATA5 CGI methylation and relative mRNA expression in tumor and adjacent normal tissues. Solid lines connect the subgroup of paired tissues (tumor tissue = solid triangle; adjacent normal = solid squares). The regression line (dashed line) and 95% CI (grey shaded) are presented. Note that tissues exhibiting concurrent high methylation and low mRNA expression can be found in the upper left corner, whereas the occurrence of low methylation and higher relative expression in tissues is displayed in the lower right corner.
