随机方法(请说明由何人用什么方法产生随机序列):

由研究负责人通过 excel表格软件进行编号1-48,之后利用 “Rand”函数在编号后生成随机数字,将该随机数字按照升序排列,前24 个数字所对应的编号纳入试验组,后24个数字所对应的编号纳入对照组。

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

Using Microsoft Excel, the principal investigator first numbered participants sequentially from 1 to 48. The 'RAND' function was then employed to generate random numbers adjacent to each serial number. After sorting by the random numbers in ascending order, participants corresponding to the top 24 serial numbers were allocated to the experimental group, while the remaining 24 were assigned to the control group.

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:

数据主要来源于电子病历系统及放射科影像学数据库,研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入原始数据。选择电子及纸质记录表格,采用相应的数据库系统双人双机录入。原始数据在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,以备查考。电子数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,应分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。

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

The data primarily originates from the electronic medical record (EMR) system and the radiology imaging database. Researchers meticulously recorded the data in a timely, complete, accurate, and legible manner based on the subjects' original observations. Both electronic and paper-based case report forms (CRFs) were utilized, with dual-entry verification performed by two independent operators using a validated database system. Upon completion of data entry and verification in accordance with requirements, the original data were systematically archived in sequential order by identification number, accompanied by a retrievable index for future reference. Electronic data files—including databases, inspection programs, analytical programs, analysis results, codebooks, and documentation—were categorized and stored separately. Multiple backups were maintained on different disks or storage media to ensure preservation and prevent data loss or corruption.
