EoE: eosinophilic esophagitis; SD: standard deviation

^1.P values obtained by t test for continuous variables and Fisher’s exact test for categorical variables.

^2.−EoE n=5557 and +EoE n=304 for this variable due to missing data.

^3.Regions of the United States as defined by the U.S. Census Bureau.

^4.P value represents comparison of United States versus international participants.
