Table 2.

Endoscopist adenoma detection rate (ADR) changes by training period and median pre-training ADR.

	3-year pre-training period	Immediately following training	3-year post-training period
	Absolute % ADR change per quarter (95% CI)	Absolute % ADR change per quarter (95% CI)	Absolute % ADR change per quarter (95% CI)
All endoscopists, n=86	0.58 (0.40, 0.77)	3.13 (1.31, 4.94)	0.33 (0.16, 0.49)
Lower ADR endoscopists, n=43	0.43 (0.19, 0.67)	4.89 (2.42, 7.36)	0.27 (0.18, 0.51)
Higher ADR endoscopists, n=43	0.80 (0.54, 1.06)	0.73 (−1.71, 3.17)	0.40 (0.18, 0.63)

Lower vs. higher ADR endoscopists were stratified using the median ADR of 29.2% in the pre-training period (see methods).

CI, confidence interval.
