Comparison of inflammatory infiltrates and eosinophil chemotaxis-associated cells between pill-induced esophagitis and reflux esophagitis groups.

aIntraepithelial cells and the cells within stroma were displayed as the highest number in one x400 power field (0.24mm2 in area). bIntraepithelial pSTAT3-positive pattern was classified into two groups; negative and positive patterns. cThe first represents P value between total cases of pill-induced esophagitis group and reflux esophagitis group, and the second denotes P value between in distal esophagus lesion of both groups. dNS, not significant.
