随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机化方法,由不参与研究的独立设计师使用R软件生成的随机序列分配。通过中央随机化系统实施分配隐藏,将260名合格受试者等比例(每组65人)随机分配至A、B、C、D四组。

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

This study employed a block randomisation method, with allocation performed using a random sequence generated by R software by an independent designer not involved in the research. Allocation concealment was implemented via a central randomisation system, randomly assigning 260 eligible participants in equal proportions (65 per group) to four groups: A, B, C, and D.

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

Data is sourced from the hospital information system, collected during the perioperative period and postoperative recovery phase to monitor vital signs and the occurrence of adverse reactions. Throughout this process, patient privacy must be safeguarded, with regular data audits and inspections conducted.
