Comparison of two combined models of cellular indices and food allergies for the screening of pediatric eosinophilic esophagitis.

Eosinophilic esophagitis (EoE) presents with dysphagia and is associated with food allergy (FA). Although esophagoscopy remains essential for diagnosis, predictive models based on cellular indices from the hemogram and FA history have been evaluated as screening tools for EoE; however, their theoretical comparison for EoE screening has not been analyzed. This study synthesizes the current literature and compares the predictive capacity of two combined models using cellular indices and FA history for EoE screening through a diagnostic study of patients <15 years old undergoing esophagoscopy for suspected EoE at a children's hospital between 2015 and 2022.
