Notes: Predictors (CTP, MELD, BCLC scores) were sequentially added and withdrew to the initial model that encompasses NLR or PLR to find out the stability of the prognostic effect of NLR and PLR in two separate models. The NLR and hemoglobin level was stable whatever the added predictors compared to PLR. MELD score was stable in the two models.
Abbreviations: HR, hazard ratio; CI, confidence interval; M, male; F, female; ALT, alanine aminotransferase; CTP, Child–Turcotte–Pugh; MELD, model for end-stage liver disease; BCLC, Barcelona clinic liver cancer; NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; NS, not significant.
