Factors influencing renal survival from endpoint event by univariate and multivariate Cox regression.

Characteristics	Univariate		Multivariate
	HR(95%CI)	P value	HR(95%CI)	P value
Hypertension	6.5(2.9-14.5)	<0.001	3.5(1.4-8.7)	0.009
Renal impairment	10.6(4.4-25.8)	<0.001	5.8(2.2-15.4)	<0.001
Yang-deficiency BC	2.3 (1.1-5.1)	0.033	2.3(1.0-5.2)	0.041
Blood-stasis BC	2.3 (1.2-4.8)	0.019	2.5(1.2-5.2)	0.017
Proteinuria of more than 1g/d	2.4 (1.0-5.4)	0.037		NS
Hypoproteinemia	2.8(1.3-5.8)	0.007		NS
Hyperuricemia	7.3(3.3-15.8)	<0.001		NS

Hypertension: blood pressure >140/90 mmHg or requirement for antihypertensive therapy; renal impairment: eGFR<60 mL/min. Hypoproteinemia: serum albumin <35 g/L; hyperuricemia: serum uric acid >420μmol/L; NS: not significant.
