	Univariate predictors of mortality		Multivariate cox regression model †
	HR (95%CI)	p value	HR (95%CI)	p value
Age, per 1-year increase	1.08 (1.03-1.14)	0.0007	1.08(1.02-1.14)	0.007
Male sex	0.84(0.69-1.00)	0.046	1.00(0.40-2.46)	1.00
Pre-PTRA eGFR, per SD	0.96(0.93-0.99)	0.0048	0.97(0.94-1.00)	0.023
LDL, per SD	0.99(0.97-1.00)	0.032	0.99(0.97-1.00)	0.062
Uric acid, per SD	1.25(1.04-1.49)	0.020	1.10(0.90-1.33)	0.36

PTRA, Percutaneous Transluminal Renal Angioplasty; BP, blood Pressure; SBP, systolic BP; DBP, diastolic BP; eGFR, estimated glomerular filtration rate. LDL, low-density lipoprotein.
