Association of TBX2 subfamily hypermethylation with clinicopathological features in human LUAD and LUSC. Gene-level methylation β-values in 522 LUADs (two left panels) and 504 LUSCs (two right panels) were propagated from the TCGA and statistically interrogated with pathological stage and tobacco history (ever: lifetime smokers, never: non-smokers). Kruskal-Wallis test was used to statistically examine differences in methylation β-values of the TBX genes by pathological stage. Wilcoxon rank sum test was used to statistically analyze methylation β-values based on tobacco exposure. All statistical analyses and plots were performed and generated using the R language and environment.
