- The parameter estimates (95% confidence interval) indicate the change in EWD per 1 standard deviation increase in arterial index. All parameter estimates accounted for the variance explained by age, sex, heart rate and body height and weight. AP, central PP and PWV were additionally adjusted for MAP. Pint indicates the P values for an interaction between each arterial index and sex in predicting EWD. aData on arterial stiffness was available in 157 men and 117 women. AP indicates augmentation pressure, BP blood pressure, MAP mean arterial pressure, PP pulse pressure, PWV pulse wave velocity
