Relationships of Measured Iohexol GFR and Estimated GFR With CKD-Related Biomarkers in Children and Adolescents

eGFRCKiDfull closely approximated mGFR to describe relationships with CKD-severity indicators and progression in this pediatric CKD population. eGFRCKiDbed offered similar inferences, but associations were attenuated and rate of progression was overestimated. The eGFRCKiDfull equation from 2012 is preferred for pediatric research purposes.
