Linear and multilinear regression considering pulse pressure as the dependent variable.

Variable(s)	R 2	β	P
SMI	0.49	−0.226	<0.05
Model 1	0.94	0.157	ns
Model 2	0.136	0.104	ns
Model 3	0.174	0.98	ns

SMI = skeletal muscle index; Model 1 = SMI plus age; Model 2 = Model 1 plus metabolic syndrome, smoking status, hypertension, and diabetes mellitus type II; Model 3 = Model 2 plus height and functionality.
