Multivariable stepwise linear regression analysis of peripheral artery stiffness in 105 diabetic patients

Items	β	Adjusted R2	Adjusted R2 change	P
Age (years)	0.470	0.279	0.279	<0.001*
Log-leptin (ng/mL)	0.259	0.364	0.085	0.001*
Hypertension	0.197	0.395	0.031	0.011*

Data for BUN and leptin levels showed skewed distributions and therefore were log-transformed before analysis. *P<0.05 was considered statistically significant in multivariable stepwise linear regression analysis (adopted factors: Age, hypertension, height, body fat mass, SBP, DBP, log-BUN, GFR, and log-leptin). BUN: Blood urea nitrogen, GFR: Glomerular filtration rate, DBP: Diastolic blood pressure, SBP: Systolic blood pressure
