Model 1: non-adjusted.

Model 2: adjutesd age, gender and race.

Model 3: adjutesd age, gender, race, education, marital, PIR, smoke, alcohol, eGFR, DM, CHD, antiHyperlipidemic and antiHypertensive.

PIR, poverty-to-income ratio; eGFR, estimated glomerular filtration rate; DM, diabetes mellitus; CHD, coronary heart disease.
