Prevalence (n, %) of eosinophils present, low-grade eosinophil counts (ie, 1–4 eosinophils/HPF), and possible (5–14/HPF), probable (15–19/HPF) or definite (⩾20/HPF) eosinophilic oesophagitis at both oesophageal sites evaluated (2 cm above the Z-line and at the Z-line) in the Kalixanda study population, mean age and proportion of men
| N (%) (95% CI) | Mean age (years) | Proportion of men (%) | |
|---|---|---|---|
| EO, eosinophilic oesophagitis; HPF, high-power field. | |||
| *In three cases, biopsy specimens from 2 cm above the Z-line were not available for evaluation in absolute number but did not contain eosinophils in the initial analysis. Biopsy specimens taken at the Z-line were not available for evaluation in absolute number in six cases; five of these were classified as mild, and in one case there were no eosinophils in the initial analysis. | |||
