^*Models adjusted for age, gender, race, diabetes, hypertension, BMI, coronary artery disease, congestive heart failure, cerebrovascular disease, peripheral vascular disease, hemoglobin and eGFR

BMI- body mass index; CKD- chronic kidney disease; OR- odds ratio

Hemoglobin Q1- <11.7 g/dl; Q2– 11.7–12.9 g/dl; Q3– 12.9–14.0 g/dl; Q4 - >14.0 g/dl
