^aUSMSTF adjusted proportion of successful cecal intubations excludes incomplete colonoscopies due to poor bowel preparation and severe colitis.

^bNumber of pathologically confirmed adenomas/number of colonoscopies ^c,d Proportion of males^c or females^d ≥50 years old, first time colonoscopy with pathologically confirmed adenoma

^eAverage withdrawal time of procedures where no lesions were detected

^fOnly 2 colonoscopies performed on this patient cohort;

^gOnly 3 colonoscopies performed on this patient cohort.

% = percent; min = minutes; # = number, serious adverse events (SAEs) reported as totals.
