Factors associated with pulse pressure (n = 446) in the whole cohort as well as pulse-wave velocity (PWV, n = 213), TACI (n = 206) and aortic augmentation index HR75 (AIX, n = 148) in blood donors and patients with CKD in a hierarchical regression model (dependent variables: pulse pressure, PWV, TACI or AIX, Model 1 includes age, sex, calcium, phosphate, magnesium and albumin, Model 2 further includes zinc), shown with regression coefficients (beta) and levels of significance (P-value; bolded if P < .05). Here, ALB is linked to chronic kidney disease.
