| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| asymptomatic subjects aged 50-69 participating to regional screening program and undergoing outpatient colonoscopy for positive
 immunologic fecal occult blood test

| E.4 | Principal exclusion criteria | 
| -	patients undergoing colonoscopy as primary screening test -	patients undergoing colonoscopy for symptoms or post-polipectomy/
 cancer surveillance
 -	patients with history of negative large bowel endoscopy within the
 previous 5 years
 -	patients with personal history of hereditary syndromes – FAP, HNPCC
 -	patients with history of colonic resection and inflammatory bowel
 disease
 -	patients with a history of radiation therapy to abdomen or pelvis
 -	patients with a history of severe cardiovascular, pulmonary, liver or
 renal disease
 -	patients with unstable psychiatric illness
 -	patients at risk for inhalation
 -	patients on ant-platelet therapy or anticoagulation at the time of
 endoscopy procedure, preventing polyp resection
 -	patient with known hypersensitivity or contraindications (i.e., patients

 to the study product
 -	patients who are not able or refuse to provide informed written
 consent

 > 10mm, and/or villous component, and/or high grade dysplasia)
 -	Proportion of patients with at least one flat/depressed adenoma,
 according to Paris classification
 -	Proportion of patients with at least one proximal sessile serrated
 adenoma/polyp
 -	Number of total adenomas, advanced adenomas, proximal
 adenomas, proximal advanced adenomas, flat/depressed adenomas
 -	Patient tolerability and acceptability, as assessed by a nurse before
 colonoscopy
