随机方法(请说明由何人用什么方法产生随机序列):

由统计分析师使用 SAS 9.4 软件 生成随机分配序列,采用区组随机化 + 分层随机化相结合的方法。 分层因素:按年龄分层(<40 岁、≥40 岁);同时按研究中心分层,控制中心效应。 区组设置:采用可变区组,区组大小为 4 或 6,避免分配结果被预判。 随机分配执行:随机序列生成后依托第三方统计机构搭建的中央随机化系统完成分配隐藏与现场随机,研究者无法提前获知分组结果。

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

Sequence generation: The random allocation sequence is generated by a statistical analyst using SAS 9.4 software, with block randomization combined with stratified randomization. Stratification factor: Age (<40 years old, ≥40 years old), as age is a key influencing factor for clinical outcomes of Poseidon Group 4 patients. Block size: Variable block sizes (4 or 6) are used to prevent prediction of group assignment. Center-based stratification: A separate random sequence is generated for each study center to control for center effects.

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:

本研究采用 电子数据采集系统(EDC)进行数据采集与管理。所有数据由经培训的研究者、胚胎学家及数据管理员依据试验方案及时、准确、完整录入。建立标准化数据核查流程,实施双份录入与交叉核对,对关键数据进行源数据核查,确保数据真实、可靠、可溯源。数据采用加密存储与权限管理,定期备份,研究结束后按规范保存至规定年限,保障数据安全与隐私保护。

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

Data collection and management are conducted using an Electronic Data Capture system (EDC). All data are recorded timely, accurately, and completely by trained investigators, embryologists, and data managers in accordance with the study protocol. A standardized data verification process is established with double data entry and cross-checking. Source data verification is performed for critical variables to ensure data authenticity, reliability, and traceability. All data are stored securely with encryption and role-based access control, backed up regularly, and retained for the required period after study completion to ensure data security and privacy protection.
