From: GPNMB methylation: a new marker of potentially carcinogenic colon lesions
Methylation frequencies (%) of GPNMB in different stages of cancer. GPNMB methylation was statistically significant for advanced tumor stages (III + IV) (P < 0.012). P values (two-sided) were generated by using chi-square test. P values are Bonferroni adjusted, and the cutoff for statistical significance is P ≤ 0.05
