CGI methylation signature is not a strong prognostic indicator of RFS in lung ADCs To investigate the association of the CGI methylation signature of the present study with RFS, it was analyzed within the TCGA-450k set, which yielded a marginally significant difference in RFS between each risk group [33.9 vs. 27.0 months; P=0.049 (log-rank test); Fig. 2A ].
