Correlation of N-myc downstream-regulated gene 1 expression with clinical outcomes of colorectal cancer patients of different race/ethnicity

Figure 4 Kaplan-Meier survival analysis of NDRG1 expression in Japanese patients with stages II and III colorectal cancers. A: Correlation of survival with NDRG1 expression stratified as negative (0) or positive (+1 to +3) and weak (0, +1) or strong (+2, +3); B: Correlation of survival with weak or strong NDRG1 staining in p53-positive tumors; C: Correlation of survival with weak or strong NDRG1 staining in patients with or without chemotherapeutic treatment, chemo (+) or chemo (-), respectively.
