LRP1B and neoplasm: In addition, as revealed by univariate Cox regression analysis, N stage (HR = 1.566, 95% CI = 1.124–2.182, p = 0.008), tumor location (HR = 2.762, 95% CI = 1.205–6.331, p = 0.016), platelet‐to‐lymphocyte ratio (PLR; HR = 1.011, 95% CI = 1.004–1.019, p = 0.016), and a low LRP1B expression status (HR = 0.432, 95% CI = 0.206–0.909, p = 0.027) were prognosis‐related risk factors for OS in the LRP1B group (Table 3).
