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:

数据采集:所有数据均采用准确报告、解释和验证的方式进行记录、处理和存储,研究人员经培训方可获得进入电子数据采集 (Electronic Data Capture, EDC) 系统的权限,将数据录入电子病历报告表 (electronic Case Report Form, eCRF)。 质量控制:研究者将审查由指定工作人员输入的数据,检查其完整性和准确性,对于数据不符和数据缺失,会创建电子数据质疑表,说明问题的性质并要求澄清问题,并通过系统发送给研究中心指定工作人员。工作人员需尽快对质疑作出回应,并对数据作必要的修订。彩色眼底照片、荧光素眼底血管造影、吲哚菁绿血管造影、OCT及OCTA图像将由独立读片师进行集中处理。数据管理人员将对eCRF中录入的数据和从读片中心和中心实验室收到的数据进行核对。

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

Data Collection: All data will be recorded, processed, and stored in a manner that ensures accurate reporting, interpretation, and verification. Researchers must undergo specific training to gain access to the Electronic Data Capture (EDC) System for entering data into the electronic Case Report Form (eCRF). Quality Control: The investigator will review the data entered by designated staff to check for completeness and accuracy. For any discrepancies or missing data, an electronic data query form will be generated to specify the issue and request clarification. This query will be sent through the system to the designated staff at the research site. The staff must respond to the query promptly and make necessary revisions to the data. Color fundus photography, fundus fluorescein angiography, indocyanine green angiography, OCT, and OCTA images will be centrally processed by independent readers. Data managers will cross-verify the data entered into the eCRF with the data received from the reading center and central laboratory.
