Model includes race, age, gender, diabetes, HTN, hyperlipidemia, BMI group, albumin and hemoglobin, malignancy, CAD, CHF, cerebrovascular disease, peripheral vascular disease, insurance, ACE/ARB, statin, beta blocker, smoking, and CKD stage. For albumin and hemoglobin we used mean value imputation with dummy indicators for missing values.
