Table 7 Stratified analysis by biopsy number for detection rate of high-risk gastric lesions in propensity score matching groups

Biopsy number	AI group (n = 7764)	Non-AI group (n = 7764)	OR (95%CI)	P value
1	0.36%	0.07%	5.53 (1.46-35.99)	0.027
2	0.45%	0.22%	2.08 (0.82-5.93)	0.138
≥ 3	2.39%	1.51%	1.60 (1.02-2.57)	0.145

OR: Odds ratio; CI: Confidence interval; AI: Artificial intelligence.
