TLR3 and cancer: The area under the curve for TLR3 expression was 0.806, which means a good measure of separability by TLR3. Using the Kaplan–Meier plotter data, we found that the expression of TLR3 was positively correlated with the overall survival (HR = 0.55, 95%CI = 0.43–0.7, P = 7.4e−07) and progression-free survival (HR = 0.67, 95%CI = 0.48–0.93, P = 0.018) in LUAD cancer patients (Figures 1D, E).
