Expression and significance of TLR4 and HIF-1α in pancreatic ductal adenocarcinoma

Figure 4 Kaplan-Meier analysis overall survival depending on TLR4 and HIF-1α expression in pancreatic ductal adenocarcinoma. A: The mean survival of patients with negative TLR4 expression in tumor tissues was significantly longer than those with TLR4 positive expression (P = 0.011); B: The mean survival of patients with negative HIF-1α expression in tumor tissues was significantly longer than those with HIF-1α positive expression (P = 0.005); C: Survival of patients with both negative TLR4 and HIF-1α expression was significantly longer than those with both positive TLR4 and HIF-1α expression (P = 0.014).
