	PLR	1.01 (1.00-1.01)	< 0.001
For AKI after postoperative day 2	NLR	1.28 (1.14-1.29)	< 0.001
	Delta-NLR	1.21 (1.14-1.29)	< 0.001
	PLR	1.10 (1.00-1.02)	< 0.001
For AKI after postoperative day 3	NLR	1.15 (1.07-1.16)	< 0.001
	Delta-NLR	1.12 (1.07-1.16)	< 0.001
	PLR	1.00 (1.00-1.01)	0.037
For AKI after postoperative day 4	NLR	1.15 (1.05-1.24)	< 0.001
