Urinary Matrix Metalloproteinase-9 and Nephrin in Idiopathic Membranous Nephropathy: A Cross-Sectional Study

Table 3

Urinary levels of MMP-9 and nephrin in patients with different clinical features of idiopathic membranous nephropathy.

Biomarkers (ng/μmolUCr)	Level of proteinuria (mg/mmolCr)			eGFR (ml/min/1.73 m^2)
	<350; ()	>350; ()	value	>90; ()	<90; ()	value
MMP-9	0.40; 0.21-0.85	1.11; 0.58-2.74	0.014	0.50; 0.21-1.23	2.02; 0.51-3.62	0.020
Nephrin			0.384			0.144

UCr: urine creatinine; Cr: creatinine; eGFR: estimated glomerular filtration rate; MMP-9: matrix metalloproteinase-9.
