Focusing on each patient, four of nine patients (patients 1, 4, 5, and 7) in the unsuppressed PRA group had chronic kidney disease (defined as an eGFR less than 60 mL/min/1.73 m2) or a urine albumin-to-creatinine ratio (UACR) > 30 mg/g creatinine [49]. Here, ALB is linked to chronic kidney disease.
