SFRP4 expression correlates with epithelial mesenchymal transition-linked genes and poor overall survival in colon cancer patients

Figure 4 Overall survival of colon cancer patients with low, intermediate or high SFRP4 expression. A: Patients expressing higher levels of SFRP4 (red line) had poor survival compared to those expressing lower SFRP4 levels (blue line); (B) When a three group analysis was performed, patients with higher SFRP4 expression (red line) presented with poor overall survival compared to patients with intermediate (white lines) or low expression (blue line).
