2. Figure 1
Technique for determining EDmax. Full-column image of maximally distended esophagus. Maximum and minimum diameter selected between aortic arch level and esophageal ampulla/hiatal hernia (asterisk). In this case of small caliber esophagus, the EDmax and EDmin are 21 and 18 mm, respectively.

3. Figure 2
EDs are decreased in EoE. Baseline EDmax was significantly decreased in EoE at 19 vs 24 mm in healthy control subjects (P = .004; **statistical significance). Similarly, baseline EDmin trended toward being lower at 16.3 vs 20.2 mm in control subjects (P = .06). EDmin of patient with EDminE of 10.8 mm (narrowing distal to segment from which EDmin and EDmax were measured) is indicated with a star symbol.

4. Figure 3
Significant increase in poststeroid EDmax only seen in subset of those with abnormal baseline EDmax. Median increase in poststeroid EDmax was not statistically significant (P = .15). However, significance was demonstrated in a subset analysis of the 6 individuals with baseline abnormal EDmax (2 mm; P = .01; **statistical significance). Note: 2 patients had the same prepost values of EDmax, which explains why there are 5 visible plots to represent 6 patients. Similarly, with EDmin (data not illustrated), posttreatment increases were not significant in the whole group (P = .1) but did reach significance when considering only the 5 individuals with baseline abnormal EDmin (3 mm; P = .02). Esophagrams were reproducible among controls, as indicated by insignificant variance (P = .44).
