随机方法(请说明由何人用什么方法产生随机序列):

随机化分配(1:1比例)通过计算机生成随机序列,能有效平衡两组间在年龄、既往疾病史、Hp治疗史、合并用药情况及生活习惯(如吸烟、饮酒)等基线特征上的差异,最大程度减少选择偏倚,确保组间具有高度可比性

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

Randomization (in a 1:1 ratio) will be performed using a computer-generated random sequence. This approach effectively balances potential baseline differences between the two groups, including age, medical history, history of H. pylori treatment, concomitant medications, and lifestyle habits (e.g., smoking and alcohol consumption), thereby minimizing selection bias and ensuring high comparability between the groups.

盲法:

鉴于试验组与对照组在抗生素种类、给药频次及用药逻辑上存在差异,为保障研究参与者用药安全,本研究采用“结果评估者盲法”设计。虽然研究参与者与临床医生为开放标签,但负责核心疗效指标判定的13C尿素呼气试验(UBT)检测人员均对研究参与者的分组信息处于盲态。这种“第三方评估”模式有效规避了评估者主观意识对主要终点数据的干扰。

Blinding:

To ensure patient safety amidst variations in antibiotic types, dosing frequencies, and administration regimens between the arms, this study employed an outcome assessor-blinded design. While open-label for participants and investigators, the laboratory staff conducting the urea breath test (UBT) for the primary efficacy assessment remained blinded to treatment allocation. This independent evaluation approach mitigates subjective assessor bias and guarantees the integrity of the primary endpoint data.

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:

鉴于本项目不使用专门的EDC系统,因此数据管理流程为“纸质/原始电子记录 →PDF版病例报告表 (CRF) →中心数据库”的模式。本研究项目数据采集及管理采用电子化PDF表单作为数据采集载体。数据统一存储于牵头中心(湘雅医院)研究负责人的专用电脑中,并进行本地及离线备份。管理制度经过系统验证且具有痕迹管理和用户权限管理的模式。数据管理员(由研究团队指定成员担任)根据方案设计CRF,CRF中包含除外部数据之外方案中规定的全部数据点。各分中心研究人员在访视现场记录原始数据。研究护士或临床研究协调员 (CRC)将原始记录录入至PDF版CRF中。录入时需确保数据的真实性、准确性与完整性。录入完成后的PDF需由该中心研究负责人电子签名确认。各参与单位定期将加密后的PDF文件通过安全途径传送至牵头中心负责人处汇总。

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

Since a dedicated EDC system is not used, data will flow from paper/original electronic records to PDF Case Report Forms (CRFs), and ultimately into a central database. Electronic PDF forms serve as the data collection tool. All data will be centralized on a secure, dedicated computer managed by the Principal Investigator at the lead center (Xiangya Hospital), backed up both locally and offline. The validated management system features an audit trail and role-based access controls. The designated data manager is responsible for designing the CRF to cover all protocol-required variables (excluding external data). Site investigators will capture raw data in source documents at point-of-care. A study nurse or Clinical Research Coordinator (CRC) will then transcribe these records into the PDF CRFs, guaranteeing data authenticity, accuracy, and integrity. Completed PDFs require an electronic signature from the site's Principal Investigator for validation. Finally, participating centers will periodically transfer encrypted PDF files through secure pathways to the lead center for central consolidation.
