C-index, concordance index; 95% CI, 95% confidence interval; AIC, Akaike Information Criterion; BIC, Bayesian Information Criterion; LMR, lymphocyte-to-monocyte ratio; IgG, immunoglobulin G; TNM, tumor/node/metastasis; OS, overall survival; P-values are calculated based on normal approximation using function rcorrp.cens in Hmisc package
