Fig 1 Methods flowchart. Retrospective analyses to (1) identify cases of colonic eosinophilia; (2) determine the diseases associated with colonic eosinophilia; and (3) estimate the prevalence of EC were performed using 2 independent approaches by searching the pathology and electronic medical record (Epic) databases as outlined by the flowchart. The dotted line indicates the point at which an in-depth chart review was conducted.
