Multivariate Cox regression analysis of patient survival in 144 HD-patients during the follow-up.

	RR	95% CI	P
Serum albumin 1 g/L	0.812	0.722–0.913	0.001
Log BNP	2.801	1.070–7.332	0.036
Diabetic status present	2.859	1.159–7.050	0.023

The original model included age, diabetic status, hemoglobin, serum albumin, hypersensitive C reactive protein(HsCRP) and log-transformed BNP.
