Characteristics of the pediatric, eosinophilic esophagitis study cohort

Characteristics	Statistics
N	46
Age (year ± SD)	8.2 ± 4.2 (median 6.9, range 2.4–17)
Age at diagnosis	6.1 ± 4.4 (median 4.4, range 0.8–17)
Sex (% male)†	100
Race (% white)†	97.8
Duration since histological diagnosis (years ± SD)	2.4 ± 1.6 (Range 0.2–7.3)
Treatment (%)	93.5
Diet only (%)	30.4
Swallowed steroids only (%)	28.3
Diet and swallowed steroids (%)	34.8
Peak eosinophil count (median [IQR, range])	35.5 (7.8–88.8, 0–295)
Disease activity* (% of cohort)
Active disease count (eos ≥ 15 hpf)	71.7
Intermediate count (15 > eos ≥ 6 hpf)	6.5
Low count (6 > eos > 0)	15.2
None (eos = 0)‡	6.5
Distal eosinophil count (median [IQR, range])	27.5 (7.8–77.3, 0–295)
Proximal eosinophil count (median [IQR, range])	4 (0–35, 0–295)

^*Activity was based on the peak eosinophil count (e.g. maximum of the proximal and distal counts).

Eos, eosinophils; hpf, high-power field; IQR, interquartile; SD, standard deviation

^†The inclusion of only males and primarily whites was an inclusion criteria for the analysis set to minimize heterogeneity.

^‡All indivduals with no eosinophils were treated.
