Stepwise regression analysis (t value) of the association between some independent variables and BNP in CKD-G5D patients.

BNP (pg/mL)	Independent variables					Model R2
	CRP (mg/L)	Creatinin (mg/dL)	Na (mmol/L)	K (mmol/L)	sRAGE (pg/mL)
	2.44	0.84	−0.81	1.40	2.72	0.20
p value	0.017	0.40	0.42	0.17	0.008
Constant value
Regression coefficient	1652.06				2.49
SE regression coefficient	676.00				0.92

CRP: C-reactive protein; sRAGE: soluble receptor of advanced glycation end products; SE: standard error.
