Distribution of proteinuria and eGFR. The median values for eGFR are shown as vertical lines, and the median 24-h urine protein is shown as horizontal lines in both panels. A) Males, n = 300, median eGFR = 81.0 mL/min/1.73 m2, and median proteinuria = 572 mg/24 h. B) Females, n = 306, median eGFR = 88.0 mL/min/1.73 m2, and median proteinuria = 180 mg/24 hr.
