Optimal cutoff values of the preoperative inflammatory markers for discriminating between the POD and non-POD groups.

Inflammatory Markers	Cutoff Value	AUC (95% CI)	Sensitivity	Specificity	p Value
NLR	2.26	0.60 (0.56–0.64)	0.63	0.53	<0.001
MLR	0.26	0.61 (0.57–0.65)	0.62	0.58	<0.001
PLR	233.90	0.52 (0.47–0.56)	0.16	0.90	0.464
CAR	0.38	0.63 (0.59–0.67)	0.57	0.66	<0.001

AUC, area under the curve; NLR. neutrophil-to-lymphocyte ratio; MLR, monocyte-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; CAR, CRP-to-albumin ratio.
