Intestinal metaplasia	0	None	None
	1	Mild	Within the antrum

Endoscopic atrophy was assessed by the Kimura-Takemoto classification (15) and classified into six grades: Close (C)-I, C-II, C-III; and Open (O)-I, O-II, and O-III.

The total score was summed from each score of 5 parameters, with a maximum score of 8.
