Figure 7From: Gene promoter methylation assayed in exhaled breath, with differences in smokers and lung cancer patients Methylation density of DAPK promoter by stage in cancer cases. The methylation density of DAPK promoter in EBC samples from different stages of lung cancer was compared by ANOVA multiple group comparison. There was no significant difference in methylation density between lung cancer stages(n = number of subjects) (p = 0.728).Back to article page
