Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Adenoma detection rate, evaluated by the techniques of linked color imaging (LCI), white light imaging (WLI) and blue laser imaging (BLI-bright) and confirmed by a blinded pathologist within 7 days of the colonoscopy. | — |
Secondary
| Measure | Time frame |
|---|---|
| Number of adenomas per patient, evaluated by the number of polyps removed during the colonoscopy of each patient, whose histology confirmed the diagnosis of adenoma, about 7 days after the colonoscopy. Colonoscope withdrawal time evaluated in minutes from the cecum to the anal margin. | — |
