| 指南使用者： | 该指南适用于各级医院、基层社康中心、疾病预防控制中心等卫生机构。指南的使用人群为全国各民族、地区的一般人群。 |
| Guide users： | The guidelines apply to hospitals at all levels, ground-level community health centers, Centers for Disease Control and prevention and other health institutions. The users of the guidelines are the general population of all ethnic groups and regions in the country. |
| 证据分级方法： | 采用GRADE方法对针对胃癌风险相关证据体质量进行评价。根据GRADE方法，将证据质量分为高、中、低、极低四个等级。在证据分级过程中，考虑五个降级因素——局限性、不精确性、不一致性、不直接性以及发表偏倚，和三个升级因素——效应量大、剂量反应关系以及可能的混杂因素（负偏倚）。完成证据分级后，将通过证据总结表呈现证据。 |
| Evidence grading method： | GRADE method will be used to evaluate certainty (quality) of evidence associated with the risk of gastric cancer. According to GRADE method, the quality of evidence is classified into four grades: high, moderate, low and very low. Five downgrading factors (risk of bias, inconsistency, indirectness, imprecision, and publication bias) and three escalation factors (large effect, plausible confounding, and dose response gradient) are considered in the evidence grading process. After grading the evidence, the evidence will be presented through the "summary of findings" table. |

| 指南制订的目的： | 目前尚缺乏循证指南来指导公众进行胃癌风险评估，并针对性进行预防干预。因此，本指南的目的是对胃癌风险评估、高风险人群预防干预措施的相关证据进行系统梳理总结，形成指南，来促进有效胃癌防控。 |
| Purpose of the guideline： | The aim of this guideline is to systematically sort out and summarize the relevant evidence of gastric cancer risk assessment and prevention and intervention measures for high-risk groups, and form guidelines to promote effective prevention and control of gastric cancer. |
