Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
2. For every enrolled patient, follow-up esophagogastroduodenoscopy were conducted in the 3rd and 5th years after the baseline examination. If high-risk endoscopic features for gastric cancer (i.e., active Helicobacter pylori infection or atrophic gastritis classified as C2-O3 according to the Kimura-Takemoto classification) were observed during the baseline examination, an additional follow-up esophagogastroduodenoscopy was performed in the 1st year after the baseline examination.
3. Clinical characteristics, gastric neoplasia-related blood biomarkers, the extent of atrophic gastritis and other endoscopic findings were collected in baseline and follow-up esophagogastroduodenoscopy. For patients whose baseline esophagogastroduodenoscopy indicates open-type atrophic gastritis (Kimura-Takemoto classification O1-O3), blood samples will be collected for whole-genome sequencing at the time of the baseline and the final follow-up examination.
4. Enrolled patients were followed up until gastric neoplasia was detected, up to a maximum of 5 years.
5. After the study was completed, a prediction model for predicting gastric neoplasia in patients with atrophic gastritis was developed.

Inclusion Criteria
2. Meets the definition of a high-risk population for gastric cancer, which includes one or more of the following: (1) Residence in a high-incidence region for gastric cancer (2) Helicobacter pylori (Hp) infection (3) History of chronic atrophic gastritis, gastric ulcer, gastric polyps, post-gastrectomy status, hypertrophic gastritis, pernicious anemia, or other precancerous gastric conditions (4) First-degree relatives of patients with gastric cancer (5) Other risk factors for gastric cancer such as high salt intake, frequent consumption of pickled foods, smoking, or heavy alcohol use
3. No gastric cancer or precancerous lesions detected on initial esophagogastroduodenoscopy, yet with endoscopic features consistent with high-risk endoscopic features. High-risk endoscopic include: (1) Active Helicobacter pylori infection (2) Atrophic gastritis (Kimura-Takemoto classification C1-O3)

Exclusion Criteria
2. History of partial or total gastrectomy
3. ASA physical status classification of 3 or higher

5. Pregnancy or lactation
6. Severe cardiac, pulmonary, hepatic, or renal disease
7. Concomitant other malignant tumors or severe infectious diseases
