Survival classification tree for adenocarcinomas. Survival classification tree was built with seven CpG sites as well as covariates using the merged data of discovery and validation sets among adenocarcinoma cases (a), which identified five clusters with significantly different survival curves (b). Cox regression was used to compare the outcomes among clusters (cluster 4 as reference) and represented by hazard ratio (HR), 95% confidence interval (95%CI), and the P value (c)
