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:

采用统一CRF/Excel数据库双人核对录入。关键变量(球囊规格、最大扩张直径、PRP制备参数、IUS测量值)实行二级核查。IUS尽量由固定超声医师按统一报告规范执行,测量取三次平均。IUS原始图像/视频及关键内镜图像以受试者编号匿名化保存,建立“图像—数据”对应索引;建议对至少10%的IUS测量值进行第二观察者复核并记录一致性(探索性)。研究中仅收集与本研究相关信息,采用受试者编号进行去标识化管理;资料保存期限按医院及适用法规要求执行

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

A unified CRF/Excel database is used for double-person verification and entry. Key variables (balloon specifications, maximum expansion diameter, PRP preparation parameters, and IUS measurement values) are subject to secondary verification. IUS should be carried out by a fixed ultrasound physician as much as possible in accordance with a unified reporting standard, and the average of three measurements should be taken. The original IUS images/videos and key endoscopic images were anonymized and saved with subject numbers, and a "image-data" corresponding index was established. It is recommended to conduct a second observer review of at least 10% of the IUS measurements and record the consistency (exploratory). Only information related to this study was collected in the research, and the subject numbers were used for de-identification management. The retention period of the data shall be implemented in accordance with the requirements of the hospital and applicable regulations
