Number of participants that the trial has enrolled

191

Results

The mean number of FPs and median ET per colonoscopy were significantly lower in the post-update group than those in the pre-update group. Mucosal tags, bubbles, and folds had the strongest association with decreased FP post-update.

Baseline Characteristics

The patient and procedural characteristics were comparable between the two groups.

Participant flow

The CADe was used in 191 ofthese cases, and video was recorded (94 in the pre-update group and 97 in the post-update group) involving three non-expert and five expert endoscopists were recorded. Six videos were excluded from the analysis because they were not properly recorded or contained no sound. PSM was conducted using eight factors, after which there were 146 colonoscopy videos (73 in each group).

Adverse events

Nothing in particular

Outcome measures

The primary outcome measure was the number ofFPs per colonoscopy. Secondary outcome measures included the number ofFPs per minute, excessive time spent by the endoscopists on FP (ET), causes ofFP, number of true positives (TP), ADR, polyp detection rate (PDR), and number of adenomas per colonoscopy (APC).
