Fig. 4From: The detection of specific hypermethylated WIF1 and NPY genes in circulating DNA by crystal digital PCR™ is a powerful new tool for colorectal cancer diagnosis and screeningComparison of methylation according to histology, tumor stages and mutation status. Comparison of the methylation of WIF1 and NPY genes according to A) the histology of the tumor (ADC-WD or ADC-PD). Non-parametric Mann-Withney test. B) Tumor stage (stage I and II, III or IV). Non-parametric Kruskal-Wallis test. C) The mutated or non-mutated status of the tumor. Non-parametric Mann-Whitney test. D) Tumor tissues compared to the adjacent healthy tissues. Non-parametric Mann-Withney test in paired series. ADC-WD: well-differentiated adenocarcinoma, ADC-PD: partially differentiated adenocarcinomaBack to article page
