Figure 1From: Promoter hypermethylation of tumor suppressor genes correlates with tumor grade and invasiveness in patients with urothelial bladder cancerComparison of Normalized index of methylation (NIM) for the tumor suppressor genes. a Between normal bladder mucosa (NB) and muscle invasive high grade (IHG) urothelial bladder cancer (*p-value for APC and MGMT was < 0.001) b Between muscle invasive high grade (IHG) and non-muscle invasive low grade (NILG) urothelial bladder cancer (*p-value for RASSF1A, APC and MGMT was <0.001 each-*Mann–Whitney-U Test).Back to article page
