随机方法(请说明由何人用什么方法产生随机序列):

仅前瞻性阶段采用随机化;采用区组随机(区组长度4–6),由独立统计师预先生成随机序列并封存于不透光信封;患者签署知情同意后由研究协调员现场拆封完成1∶1分配。

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomization was applied only in the prospective phase. Block randomization (block length: 4–6) was adopted; an independent statistician generated the random sequence in advance and sealed it in light-proof envelopes. After patients signed the informed consent form, the research coordinator opened the envelopes on site to complete the 1:1 allocation.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

由于干预措施(进镜时机)无法对操作者设盲,故采用开放标签;但结局评估者和数据统计者设盲。

Blinding:

Blinding of operators was impossible given the intervention (timing of endoscope insertion), so an open-label design was used. Outcome assessors and data analysts remained blinded.

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Data are available upon reasonable request. Deidentified participant data will be shared with researchers who submit a methodologically sound proposal to [contact email] and sign a data use agreement.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据采集:统一记录受试者唯一研究编号(回顾性阶段采用 “年份 - 序号” 编码,前瞻性阶段采用 “前瞻 - 序号” 编码)、年龄、性别、身高、体重、ASA 分级(Ⅰ-Ⅱ 级)、既往病史(高血压、糖尿病等)、检查类型(胃镜 / 肠镜 / 联合);前瞻性阶段额外记录知情同意书签署日期、签署人、紧急联系人信息;回顾性阶段补充病历号、检查日期等溯源信息。 数据管理:前瞻性阶段:研究人员在完成纸质 CRF 填写与一级核查后,24 小时内登录 EDC 系统,将数据准确录入 eCRF;HR、PI 等监护仪监测数据支持通过设备接口直接导入系统,导入后需由录入人核对确认并签名。 回顾性阶段:由 2 名数据提取人员将纸质 CRF 整理后,独立录入 EDC 系统,系统自动对比两人录入数据,标记不一致字段,由主要研究者仲裁后确定最终数据。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data Collection Uniformly record the unique research number of each subject (coded as "Year-Sequence Number" in the retrospective stage and "Prospective-Sequence Number" in the prospective stage), age, gender, height, weight, ASA classification (Grade Ⅰ-Ⅱ), past medical history (hypertension, diabetes mellitus, etc.), and examination type (gastroscopy/colonoscopy/combined); additionally record the signing date of the informed consent form, signatory, and emergency contact information in the prospective stage; supplement traceability information such as medical record number and examination date in the retrospective stage. Data Management Prospective Stage: After completing the filling and first-level verification of the paper CRF, researchers shall log in to the EDC system within 24 hours and accurately enter the data into the electronic Case Report Form (eCRF); Monitor data such as HR and PI can be directly imported into the system through the equipment interface, and the importer shall verify, confirm and sign after import. Retrospective Stage: Two data extractors shall sort out the paper CRF and independently enter the data into the EDC system. The system will automatically compare the data entered by the two extractors, mark inconsistent fields, and the final data shall be determined after arbitration by the principal investigator.
