Table 3 Correlation between serum NGAL 6 h postoperative and change in creatinine in the AKI group after 2 days in the AKI group

Parameter	Mean ± SD	Correlation coefficient (r)**	p value
Creatinine level at 6 h	0.94 ± 0.05	− 0.109	0.82
Creatinine level at 12 h	1 ± 0.06	− 0.045	0.92
Creatinine level at 24 h	1.09 ± 0.07	0.33	0.47
Creatinine level at 48 h	1.53 ± 0.09	0.857	0.014*

*p value less than 0.05 is considered statistically significant p value < 0.001 is highly significant
