随机方法(请说明由何人用什么方法产生随机序列):

随机化由西安交通大学第一附属医院公共卫生中心负责,采用中央分配的区组随机化,区组长度不固定(2,4或6),以试验中心作为分层因素,按试验中心分别生成1:1比例的随机序列。按照上述规则由R软件(版本 4.2.0)生成3个随机序列;然后,将随机序列制作为3张带涂层的随机数字卡片。

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

Randomization was conducted by the Public Health Center of the First Affiliated Hospital of Xi’an Jiaotong University. A centralized block randomization with varying block lengths (2, 4, or 6) was used, with the study center as a stratification factor. Randomization sequences in a 1:1 ratio were generated separately for each study center. Following the above rules, three randomization sequences were generated using R software (version 4.2.0). Subsequently, the sequences were made into three coated random number cards.

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:

参加研究人员组织统一培训,培训内容包括研究方案、表格填写规范、设备操作规范以及人员分工,并进行量表评估一致性评价,保证采集数据的质量。试验过程中每个中心固定由1名医师根据受试者入组顺序及对应随机数进行试验分组。并指派未参与治疗和分组的医生进行结局指标的评估。

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

All participating researchers attended a centralized training session. The training covered the study protocol, standards for completing case report forms, equipment operating procedures, and division of responsibilities. A consistency assessment for scale evaluation was also conducted to ensure data quality. During the trial, one fixed physician at each center assigned participants to groups according to the order of enrollment and the corresponding randomization numbers. In addition, a physician who was not involved in the treatment or group allocation was designated to perform outcome assessments.
