Risk scoring system combined with traditional Chinese medicine constitution identification improves colorectal advanced neoplasms screening effectiveness for early colonoscopy

Table 2 Distribution of colorectal neoplasms and Asia-Pacific Colorectal Screening score risk groups

Lesion characteristics	AR	MR	HR	P value	OR (95%CI)
Negative	358 (25.0)	700 (49.0)	235 (16.4)	MR vs AR: 0.007	MR vs AR: 0.4 (0.2-0.8)
				HR vs AR: < 0.001	HR vs AR: 0.1 (0.0-0.2)
				HR vs MR: < 0.001	HR vs MR: 0.3 (0.2-0.4)
Advanced adenoma	12 (0.8)	52 (3.6)	62 (4.3)	MR vs AR: 0.013	MR vs AR: 2.2 (1.2-4.2)
				HR vs AR: < 0.001	HR vs AR: 7.6 (4.0-14.4)
				HR vs MR: < 0.001	HR vs MR: 3.4 (2.3-5.1)
Colorectal cancer	0 (0)	3 (0.2)	8 (0.6)	MR vs AR: 0.555	MR vs AR: -
				HR vs AR: 0.005	HR vs AR: -
				HR vs MR: 0.004	HR vs MR: 6.8 (1.8-25.6)

Odds ratio could not be calculated as there was no colorectal cancer in the average risk group. OR: Odds ratio; AR: Average risk; MR: Moderate risk; HR: High risk; CI: Confidence interval.
