^aeGFRcrea, estimated GFR by creatinine-based Modification of Diet in Renal Disease study equation; PWV, pulse wave velocity.

^bMultivariable models include: age, gender, Omni cohort status, body mass index, heart rate, mean arterial pressure (for models other than mean arterial pressure), diabetes, fasting blood glucose, total/high density lipoprotein cholesterol, lipid lowering medication use, triglycerides, hypertension treatment, hormone replacement therapy in women, current smoking status and prevalent cardiovascular disease.
