Number of participants that the trial has enrolled 825
Results 
Among 826 patients enrolled, 782 patients
had at least one follow-up, with a median follow-up of 2.97 years. Authentic metachronous gastric cancers developed in 66 patients. The highest quartile of the miR-124a-3 methylation levelhad a significant univariate HR (95% CI) (2.17 (1.07 to 4.41); p=0.032) and a multivariate-adjusted HR (2.30(1.03 to 5.10); p=0.042) of developing authentic metachronous gastric cancers. Similar trends were seen for EMX1 and NKX6-1.

Other
Other related information Patients with early gastric cancer, aged
40-80 years, who planned to have, or had undergone,ER, were enrolled at least 6 months after Helicobacter pylori infection discontinued. Methylation levels of three preselected genes (miR-124a-3, EMX1 and NKX6-1) were measured by quantitative methylation-specific PCR. Patients were followed up annually by endoscopy, and the primary endpoint was defined as detection of a metachronous gastric cancer. Authentic metachronous gastric cancers were defined as cancers excluding those detected within 1 year after the enrolment.
