Table 3.

The preoperative values of the calculated Acute Renal Failure (ARF) scores, the creatinine, and the estimated glomerular filtration rate (GFR) in relation to the AKIN-levels classified on postoperative day 4. The calculated ARF score in AKIN-levels 2 + 3 were significantly higher than in AKIN-levels 0 + 1 (4.07 ± 2.46 vs. 2.91 ± 1.83, p = 0.043)

	AKIN 0	AKIN 1	AKIN 2	AKIN 3
ARF score	2.62 ± 1.74	3.52 ± 1.84	3.75 ± 1.85	4.43 ± 1.82
	2.91 ± 1.83		4.07 ± 2.46
Creatinine (mg/dl)	0.99 ± 0.53	1.11 ± 0.33	1.03 ± 0.32	1.32 ± 0.64
	1.03 ± 0.48		1.17 ± 0.53
GFR (ml/min/1.73 m2)	91.6 ± 41.9	69.8 ± 23.7	89.8 ± 34.7	43.3 ± 23.2
	83.3 ± 33.82		68.1 ± 26,83
