*Criteria for number of eosinophils/area is '''''highly variable'''''; there is a 23X fold variation in published values and only 11% of studies actually define an area (most studies, embarassing, only give the number of eosinophils per "HPF")!<ref name=pmid17617209>{{cite journal |author=Dellon ES, Aderoju A, Woosley JT, Sandler RS, Shaheen NJ |title=Variability in diagnostic criteria for eosinophilic esophagitis: a systematic review |journal=Am.

*Most resident microscopes at the Toronto teaching hospitals have 22 mm eye pieces and have for their highest magnification objective a 40X.

It blows my mind that the people could so will fully blind and that the reviewers didn't understand this. | |||
