Table 1 Comparative analysis of the urinary NGAL concentrations among the different groups

Parameter	Control (n = 11)	AKI (n = 16)	CKD (n = 8)	RF-PYU (n = 17)	PYU (n = 19)	Non-RP (n = 10)
uNGAL (ng/mL)	3.92^a (9.05)	37.90^b (56.08)	18.96^b (11.19)	18.97^b (70.32)	15.35^b (27.663)	9.22^a (10.36)
Age (year)	6 (4)	8 (4.75)	7 (10)	5 (4)	5.5 (2.25)	4.5 (4.5)
BUN (mmol/L)	4.6^a (3.9)	49.3^d (53.6)	15.4^b (13.1)	32.5^c (20.5)	7.5^a (4.3)	6.0^a (4.11)
Creatinine (μmol/L)	97.3^a (44.2)	291.7^c (580.8)	194.5^b (92.8)	291.7^c (154.7)	106.1^a (44.2)	70.7^a (59.2)
Urine Sp. Gr.	1.02 (0.01)	1.019 (0.01)	1.014 (0.02)	1.015 (0.01)	1.015 (0.01)	1.015 (0)

Analysis of variance among and between the groups was performed by Kruskal-Wallis Test and Mann-Whitney T test individually and the median (IQR) is presented. Different superscript letters (a. b, c) represents a significant difference between two groups (p < 0.05). AKI: acute kidney injury; CKD: chronic kidney disease; RF-PYU: azotemia with pyuria; PYU: pyuria without azotemia; non-RP: diseases without any relation of azotemia and pyuria.
