随机方法(请说明由何人用什么方法产生随机序列):

采用区组随机化,区组长度为4,按1:1比例分配至试验组与对照组。随机序列由独立统计人员使用SAS软件生成。分配隐藏采用顺序编号、不透光、密封信封。

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

Block randomization with a block size of 4 will be used to assign participants to the experimental group or the control group in a 1:1 ratio. The random allocation sequence will be generated by an independent statistician using SAS software. Allocation concealment will be implemented using sequentially numbered, opaque, sealed envelopes.

盲法:

本研究为评估者盲设计。临床参数评估者及影像学阅片者对分组设盲;手术操作者及受试者因干预措施性质无法设盲。

Blinding:

This study adopts an assessor-blinded design. The clinical parameter evaluators and radiographic image reviewers will be blinded to the group allocation. The surgeons and participants cannot be blinded due to the nature of the interventions.

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:

RCT数据采用电子数据采集系统(EDC)进行录入和管理。数据实行双人独立录入并交叉核对,系统预设逻辑校验规则,确保数据真实、完整、可溯源。

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

Data for the RCT will be entered and managed using an Electronic Data Capture (EDC) system. Data will be entered independently by two investigators and cross-checked for consistency. The EDC system will incorporate pre-defined logic validation rules to ensure data authenticity, completeness, and traceability.
