Model 1: Adjusted for age, gender, race, and study site.

Model 2: Adjusted for age, gender, race, study site, diabetes, smoking, BMI, LDL, lipid lower medications, eGFR, and 25(OH)D.

Beta and 95% confidence interval are differences in mean measure of arterial function (units unique to each outcome) comparing high parathyroid hormone (> 65 pg/ml) categories to normal parathyroid hormone (< 65 pg/ml) category. PTH, parathyroid hormone, SD, standard deviation, CI, confidence interval, FMD, flow-mediated dilation, Aortic PP, aortic pulse pressure, LAE, large artery elasticity, SAE, small artery elasticity.
