The prognostic significance of the Immune parameters in the training cohort. Kaplan–Meier survival analysis showed the HCC prognosis in the group with the cutoff value of PLR (a), NLR (b), SII (c), post-PLR (d), post-NLR (e), post-SII (f), delta-PLR (g), delta-NLR (h), and delta-SII (i). PLR = platelet count/lymphocyte count; NLR = neutrophil count/lymphocyte count; SII = platelet count × neutrophil count/lymphocyte count. Post PLR = post-platelet count/post-lymphocyte count; post NLR = neutrophil count/ post-lymphocyte count; post SII = post-platelet count × post-neutrophil count/post-lymphocyte count; delta NLR = NLR − post NLR; delta PLR = PLR − post PLR; delta SII = SII − post SII
