Multivariate linear regression analysis adjusted for body mass index, mean arterial blood pressure, heart rate, diabetes, dyslipidemia, creatinine, pharmacological treatment, smoking, aldosterone, and renin showed that women of both ethnicities had higher cf-PWV (White β=0.7 m/s, P=0.030, Black β=0.5 m/s, P=0.046) compared with White men used as reference. Here, REN is linked to metabolic syndrome.
