Each item in the far left column was an outcome (independent variable). Results shown are the adjusted odds ratio of Black race and other race (compared to White race as reference) as a predictor of goals. All models also run with variables of gender, age, diagnoses of diabetes, CAD, heart failure, or hypertension.
