Table 3 Sensitivity, specificity, and positive and negative likelihood ratios for cancer alone and cancer and high‐risk adenomatous polyps.

	Sensitivity, % (95% CI)	Specificity, % (95% CI)	Positive likelihood ratio (95% CI)	Negative likelihood ratio (95% CI)
Cancer	95.9 (84.8 to 99.3)	59.2 (54.7 to 63.5)	2.35 (2.08 to 2.65)	0.07 (0.02 to 0.27)
Cancer and high‐risk adenomatous polyps	87.8 (80.1 to 92.9)	65.3 (60.6 to 69.7)	2.53 (2.19 to 2.93)	0.19 (0.11 to 0.31)

High‐risk adenomatous polyps are either >10 mm diameter or >3 polyps or both in an individual participant.
