随机方法(请说明由何人用什么方法产生随机序列):

随机序列将由不参与受试者招募与评估的独立研究统计人员,使用“randomizr”R软件包生成区组随机化序列,设定种子数以确保可重复性;然后将生成的序列装入按顺序编号、密封、不透光的随机分配信封中,或录入中央随机化系统,由临床协调员在合格受试者入组时按顺序拆封或查询系统以执行分组分配。

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

The random sequence will be generated by independent research statisticians who are not involved in the recruitment and evaluation of subjects, using the ' randomizr ' R software package to generate block randomization sequences, setting the number of seeds to ensure repeatability ; the generated sequence was then loaded into a sequentially numbered, sealed, opaque random distribution envelope, or entered into a central randomization system. The clinical coordinator would unpack or query the system in order to perform group allocation when eligible subjects were enrolled.

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:

本研究采用纸质病例记录表与电子数据采集系统相结合的方式进行数据管理。所有临床数据(如实验室结果、不良反应记录、妊娠结局)将首先准确、完整地记录于纸质病例记录表上,随后由经过培训的研究人员及时转录至基于网络的电子数据采集系统。该系统内置逻辑核查、范围检查与必填项验证功能,确保数据的准确性、一致性及完整性,并实现数据的实时加密存储与集中管理,为后续的统计分析、数据监查与溯源提供支持。

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

Data collection and management will be implemented using a combination of paper-based Case Report Forms and an Electronic Data Capture system. All clinical data (e.g., lab results, adverse event records, pregnancy outcomes) will be initially recorded accurately and completely on paper CRFs, then promptly entered by trained study personnel into a web-based EDC system. This system features built-in logic checks, range validations, and required field controls to ensure data accuracy, consistency, and completeness. It also enables real-time encrypted data storage and centralized management, providing a reliable foundation for subsequent statistical analysis, data monitoring, and audit trail.
