Table 3 Gastric cancer incidence based on endoscopic atrophy

Ref.	Population	No. of subjects	No. of cancers	Duration, yr	Gastric cancer incidence, %/yr
					Atrophy (mild)	Atrophy (moderate)	Atrophy (severe)
Shichijo et al[39], 20161,2	Post eradication	573	21	6.2 ± 4.8	0.07	0.34	1.60
Kaji et al[40], 20193	Screening	12941	63	3.7 ± 0.8	0.10	0.16	0.31
	Post eradication	2571	20	3.7 ± 0.8	0.06	0.12	0.42
Take et al[41], 20201	Post eradication	2737	68	7.1 ± 5.4	0.15	0.29	0.67

¹Mild, moderate, and severe atrophy represent Kimura-Takemoto’s C1-2, C3-O1, and O2-3, respectively.

²Incidence was divided the incidence per 10 years by 10.

³Mild, moderate, and severe atrophy represent Kyoto atrophy scores 0, 1, and 2, respectively.
