Group/Cohort |
---|
Cohort 1
Age between 1 and 16 years (before 17th birthday) and estimated (based on SCr) Schwartz GFR between 30 and 90 ml/min|1.73m2
|
Cohort 2
Age between 1 and 16 years (before 17th birthday), estimated GFR between 45 and 90 ml/min|1.73m2 based on the updated Schwartz formula, and an equal distribution of children with glomerular and non-glomerular causes of disease were enrolled (i.e., 150 within each) and the study placed an upper limit of 60% for the percent of enrolled with non-glomerular disease.
|
Cohort 3
Age between 6 months and 16 years (before 17th birthday) with non-glomerular diagnosis and duration of kidney disease less than 5 years will be enrolled.
