Design outcomes

Primary

Measure	Time frame
Difference in the number of MWFL detected at first endoscopy between the WLI and NBI groups.	—

Secondary

Measure	Time frame
1.Difference in the positive rate of MWFL detected at first endoscopy between the WLI and NBI groups. 2.To compare the number and positive rate of MWFL detected by first and second endoscopy in the NBI and WLI groups, and to examine the additional effect of MWFL detection ability in both groups. 3.Differences in MWFL detectability by years of experience of practicing physicians. 4.The relationship between MWFL detectability and the following contents will be examined. 1)oral administration period of PPIs. 2)endoscopic findings (gastric polyps, gastric mucosa findings).	—
