aModel was adjusted for age, sex, race, BMI, tobacco use, baseline urine citrate, baseline urine calcium, baseline urine volume, history of hypertension, diabetes, CVD and malabsorptive condition.
Patients with CKD during baseline were excluded from this table, leaving 426 896 patients included in this analysis.
CKD status was defined using only diagnosis codes.
