随机方法(请说明由何人用什么方法产生随机序列):

使用随机数生成器提前生成随机分配序列。所有入组的参与者被分配接受 CCSP 或 UCSP 以 1:1 的比例使用简单随机化。

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

Use a random number generator to generate a random allocation sequence in advance. All enrolled participants were assigned to receive CCSP or UCSP in a 1:1 ratio using simple randomization.

盲法:

这是一项单盲研究,治疗分配对患者设盲。由于干预的性质,无法在内镜医师水平上应用盲法。

Blinding:

This is a single-blind study, in which patients are blinded to the treatment allocation. Given the nature of the intervention, it is impossible to blind the endoscopists.

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:

病例记录表(CRF):设计包含患者基线信息、结肠镜检查结果、息肉特征、手术记录、术后随访及不良事件等,由经过培训的研究人员填写,并采用双人核对机制确保数据准确性。

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

Case Record Form (CRF): A standardized CRF will be used, including patient baseline information, colonoscopy findings, polyp characteristics, procedural records, post-procedure follow-up, and adverse events. All entries will be completed by trained researchers and verified by a second researcher to ensure data accuracy.
