About this trial
This is a pilot clinical trial of oral iron therapy in children with chronic kidney disease (CKD) and mild anemia. Eligible children will be randomized into a standard of care (iron sulfate) arm vs. no iron therapy arm for 3 months. The outcomes will include muscle strength, physical activity, and changes in eating behavior, which will be measured at enrollment and at the end of the study period.
