NLR = neutrophil-to-lymphocyte ratio; MLR = monocyte-to-lymphocyte ratio; PLR = platelet-to-lymphocyte ratio; SII = systemic immune inflammation index; SIRI = systemic inflammatory response index; OR = odds ratio; CI = confidence interval; AUC = the area under the receiver operating characteristic curve; PPV = positive prediction value; NPV = negative prediction value.
