Area under curve for preop NLR: AUC = 0.530 (0.097-0.963), (p = 0.861).

Best cut-off level for preop NLR: 9.635. Sensitivity and specificity at this level were 66.7% and 69.0%, respectively.

Area under curve for postop NLR: AUC = 0.953 (0.908-0.999), (p = 0.007).

Best cut-off level for postop NLR: 21.07. Sensitivity and specificity at this level were 100% and 91.5%, respectively.

Area under curve for NLR change: AUC = 0.941 (0.867-1.000), (p = 0.009).

Best cut-off level for NLR change: 11.25. Sensitivity and specificity at this level were 100% and 85.3%, respectively.
