Mean (±95% CIs) performance for each experience group on measures associated with the detection of polyp markers. Specific measures are: percentage of polyp markers found (a); number of polyp markers found per minute (b); percentage of the mucosal surface illuminated (for 0.5 s or more) by the colonoscope (c); and polyp markers illuminated (for 2.5 s or more) but not identified by the participant, as a percentage of all polyp markers (d). Asterisks indicate statistically significant differences between the groups
