随机方法(请说明由何人用什么方法产生随机序列): |
按扫描方式及对比剂用量随机分为传统常规组(105例)、三低组(105例)、超低剂量组(105例),由研究者本人采用简单随机化法,按1:1:1比例将受试者分配至三组,以保证组间基线特征均衡可比。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Using a simple randomization method performed personally by the investigator, participants were assigned in a 1:1:1 ratio to three groups—the conventional protocol group, the triple-low protocol group, and the ultra-low dose protocol group (105 cases each)—based on scanning protocol and contrast agent dose, to guarantee balanced baseline characteristics. |

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: |
本试验数据采集和管理由病例记录表和电子采集管理系统共同完成。病例记录表(CRF)依据试验方案制定,涵盖受试者人口学信息、疾病诊断数据、实验室检测结果及不良事件等内容,填写需保证字迹清晰,修改时需签署姓名缩写与修改时间。电子数据采用REDCap平台(EDC系统)采集,非问卷类的实验室数据等由专人录入整合并转为csv文件,数据经验证后存入SQL数据库,同时定期备份至安全服务器,确保数据安全可追溯。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection and management for this trial are conducted through both Case Report Forms (CRFs) and an electronic data capture system. The Case Report Form (CRF), developed based on the trial protocol, includes content such as participant demographic information, disease diagnostic data, laboratory test results, and adverse events. Entries must be completed with clear handwriting, and any corrections must be initialed and dated. Electronic data are collected using the REDCap platform (Electronic Data Capture system, EDC). Non-questionnaire data, such as laboratory results, are entered, integrated, and converted into CSV files by dedicated personnel. Following verification, the data are stored in an SQL database, with regular backups to a secure server to ensure data safety and traceability. |
