This retrospective observational cohort study aims to evaluate the association between hemoglobin levels and the time to resolution of diabetic ketoacidosis (DKA) in pediatric patients. The primary hypothesis is that children with anemia experience a longer duration of DKA and prolonged hospitalization compared with non-anemic children. All eligible patients aged 1-18 years who were diagnosed with DKA between 01.01.2013 and 01.01.2025 at a tertiary pediatric center will be included. Clinical, laboratory, and treatment data will be collected from electronic medical records.
