研究目的: |
本研究旨在通过半定量视觉评分法评估血管周围间隙扩大(EPVS)程度,以探究脑静脉回流障碍患者的脑内类淋巴功能,并进一步分析影响EPVS严重程度的潜在相关因素。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aims to evaluate the degree of enlarged perivascular spaces (EPVS) using a semi-quantitative visual rating scale, in order to investigate glymphatic function in patients with cerebral venous outflow disturbance. Furthermore, potential factors associated with the severity of EPVS will be analyzed. |

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: |
选择电子记录表格进行数据采集,录入数据时双人双机录入,之后对数据库进行两遍比对,所有分歧数据均由第三位资深研究者进行最终裁定。电子数据文件应分类保存,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: |
Electronic case report forms (eCRFs) were selected for data collection, with dual independent entry performed by two operators using separate computers, followed by two rounds of database verification. All discrepant data were adjudicated by a third senior investigator. Electronic data files were categorized and stored with multiple backups maintained on separate disks or storage media to ensure proper preservation and prevent data corruption. |
