Table 5 Influence of artificial intelligence assistance on detection rate of high-risk gastric lesions in different parts of stomach in propensity score matching groups, n (%)

Location of lesion	AI group (n = 7764)	Non-AI group (n = 7764)	OR (95%CI)	P value
Cardia	11 (0.14)	6 (0.08)	1.84 (0.68-4.96)	0.232
Gastric fundus	3 (0.04)	1 (0.01)	3.00 (0.31-28.85)	0.341
Gastric body	11 (0.14)	5 (0.06)	2.20 (0.77-6.34)	0.144
Gastric angle	11 (0.14)	3 (0.04)	3.67 (1.02-13.16)	0.046
Gastric antrum	35 (0.45)	23 (0.30)	1.52 (0.90-2.58)	0.117
Gastric pylorus	3 (0.04)	3 (0.04)	1.00 (0.20-4.96)	1.000

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