X-tile analyses to determine the optimal cut-off values of a FAR, b NLR, c MLR, d PLR and e SII. The optimal cut-off values of FAR, NLR, MLR, PLR and SII were 8.9, 3.0, 0.3, 201.5, and 876.0, respectively. FAR, fibrinogen-albumin ratio; NLR, neutrophil–lymphocyte ratio; MLR, monocyte-lymphocyte ratio; PLR, platelet–lymphocyte ratio; SII, systemic immune–inflammation index; AFP, alpha-fetoprotein
