Impact of Alcian blue and periodic acid Schiff expression on the prognosis of gastric signet ring cell carcinoma

Figure 5 Cancer-specific survival of patients in different groups according to the alcian blue-to-periodic acid Schiff ratio. A: 3-year cancer-specific survival (CSS) of patients with signet ring cell carcinoma grouped according to alcian blue-to-periodic acid Schiff ratio (A/P) divided into two groups (P = 0.042); B: 3-year CSS of patients grouped according to A/P divided into three groups (P = 0.067). A/P: Alcian blue-to-periodic acid Schiff ratio.
