ERBB2 and neoplasm: At univariable analysis, patient age (beta coefficient: 0.009, 95% confidence interval (CI) 0.001–0.017, P = 0.027), tumour size (beta coefficient: 0.013, 95% CI 0.005–0.021, P = 0.001), and human epidermal growth factor receptor-2 status (beta coefficient: − 0.370, 95% CI − 0.676–0.065, P = 0.017) were all predicted using NLR.
