Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome of the study is the polyp detection rate of HD-WLE and LCI. Polyp detection rates are defined as the number of patients with at least 1 polyp detected during the inspection divided by the total number of patients included in the study. | — |
Secondary
| Measure | Time frame |
|---|---|
| - The difference in mean number of polyps between HD-WLE and LCI - The difference in adenoma detection rate between HD-WLE and LCI - The difference in mean number of adenomas between HD-WLE and LCI - The difference in mean number of serrated polyps between HD-WLE and LCI - The mean duration of both endoscopic procedures LCI vs. HD-WLE: time for inspection and time for performing endoscopic resection - The sensitivity, specificity and accuracy of optical diagnosis on a per polyp basis | — |
