Stratified comparisons of IL10 CpG island methylation between tumor tissues and paired para-tumor tissues. P-values were calculated using Wilcoxon rank sum test. Stratified tests were performed according to tumor differentiation, Borrmann type, smoking history and family history of cancer. Plots are presented as median with interquartile range. A significant P-value was identified in the following subgroups: Low differentiation, III+IV Borrmann types, non-smoker patients and patients with no family history of cancer. IL10, interleukin 10; N, normal adjacent tissue; PMR, percentage of methylated reference; T, tumor tissue.
