Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Sensitivity and specificity of the eNose for detecting BE with the diagnosis made by upper endoscopy as the reference standard. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Acceptance rates for breath testing - Patient acceptability of the eNose procedure - Technical or patient related problems obtaining a read-out from the Aeonose™ - Accuracy of the eNose with which it could distinguish patients with BE from patients with GERD - Reproducibility by repeated testing - Effect of PPI use on the accuracy of the eNose for detecting BE | — |
