随机方法(请说明由何人用什么方法产生随机序列):

随机分配序列由一名独立统计师使用计算机生成的随机数字序列产生。采用了区组随机化方法,固定区组长度为6,以确保在整个试验过程中三组受试者的分布均衡。

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

The random allocation sequence was generated by an independent statistician using a computer-generated random number sequence. A block randomization method with a fixed block size of 6 was employed to ensure a balanced distribution of participants across the three groups throughout the trial.

盲法:

这是一项双盲试验,受试者和参与其护理的临床医生(包括麻醉医生、外科医生和结局评估者)均对分组分配不知情。研究药物和安慰剂由专人根据随机化列表,准备在外观完全相同的、按顺序编号的注射器中。所有溶液的外观、容量和给药程序均无法区分。

Blinding:

This was a double-blind trial in which both the participants and the clinicians involved in their care (including anesthesiologists, surgeons, and outcome assessors) were blinded to the group assignments. The investigational drug and the placebo were prepared by a dedicated staff member according to the randomization list of syringes that were identical in appearance and sequentially numbered. The appearance, volume, and administration procedure of all solutions were indistinguishable.

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:

使用预先设计好的病例报告表(CRF)收集术前、术中和术后变量数据。 为确保准确性,所有数据均被双份录入一个执行自动逻辑和范围核查的定制数据库中。一名对分组分配不知情的独立数据管理员,通过查阅原始源文件解决所有数据疑问。研究实施了定期备份和严格的访问控制,以保护数据安全及受试者隐私。

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

Data on preoperative, intraoperative, and postoperative variables were collected using a predefined case report form. To ensure accuracy, all data were double-entered into a customized database that performed automated logic and range checks. An independent data manager, blinded to group allocation, resolved any queries by referring to the original source documents. Regular backups and stringent access controls were implemented to safeguard data security and participant confidentiality.
