The purpose of this study was to inform the design of a possible clinical trial in children with chronic kidney disease. Our goals were to use the PEDSnet EHR database to:
1. Identify a population of children ages 6 months to <18 years-old with chronic kidney disease defined by an eGFR in the range 30-89 ml/min and then, and
2. Characterize their longitudinal changes in kidney function over time in order to identify a sub-group of rapid progressors.
The study was done using PEDSnet’s database version 36 with data from November 2019.
