Model 1 is unadjusted. Model 2 is adjusted for age, race, gender, high school education (yes/no), health insurance (yes/no), and family history of kidney disease or dialysis (yes/no). Model 3 is adjusted for age, race, gender, high school education (yes/no), health insurance (yes/no), family history of kidney disease or dialysis (yes/no), diabetes (yes/no), cardiovascular disease (yes/no), hypertension (yes/no), cancer (yes/no), dyslipidemia, albuminuria (yes/no), BMI, baseline, Hgb level, and smoking status. Model 4 is adjusted for age, race, gender, high school education (yes/no), health insurance (yes/no), family history of kidney disease or dialysis (yes/no), diabetes (yes/no), cardiovascular disease (yes/no), hypertension (yes/no), cancer (yes/no), dyslipidemia, albuminuria (yes/no), BMI, Hgb level, smoking status, baseline eGFR, calcium, and phosphorus. CI, Confidence interval; Hgb, hemoglobin; eGFR, estimated GFR.
