Multivariate Cox regression analysis of risk factors at baseline for all-cause mortality—log-normalized serum IS level entered as a continuous variable

Models of Patient Survival (event n = 25)	RR^a	95% CI	P
Unadjusted (GF = 18; P < 0.0001)	2.391	1.551 to 3.684	<0.0001
Model 1^a (GF = 32; P < 0.0001)	2.468	1.617 to 3.767	<0.0001
Model 2^b (GF = 25; P < 0.0001)	2.105	1.373 to 3.226	0.001
Model 3^c (GF = 29; P < 0.0001)	2.165	1.377 to 3.402	0.001
Model 4^d (GF = 19; P < 0.0001)	2.226	1.363 to 3.637	0.001

Summarizing the risk of a 1-SD (1.076) increment in log-normalized serum IS level for unadjusted model and for noncumulative models adjusted for multiple variables.

Model 1 was adjusted for age (in decades), diabetes status, and male gender.

Model 2 was adjusted for serum albumin (in 1-g/L increments), hemoglobin (in 1-g/L increments), and phosphate (in 1-mMol/L increments) levels.

Model 3 was adjusted for the aortic calcification score on computed tomography (in 1% increments) and PWV (in 1-m/s increments).

Model 4 was adjusted for the aortic calcification score on x-ray (in 1-unit increments).
