Results are from ordinary least squares regression with the listed independent variables; CRP, aldosterone, urinary sodium/creatinine, HOMA-IR, and hfPWV are log transformed; R² = model coefficient of determination; CRP=C-reactive protein, MAP=mean arterial pressure, HOMA-IR= homeostasis model assessment of insulin resistance, Urinary Na/Cr = 24-hour urinary sodium/creatinine ratio, hfPWV=heart-femoral pulse wave velocity, baPWV=brachial-ankle pulse wave velocity, faPWV=femoral-ankle pulse wave velocity
