研究目的:

在支气管舒张实验阴性的哮喘患者中,对FeNO及CaNO与小气道功能相关性进行研究,同时探讨FeNO、CaNO联合小气道功能指标对支气管舒张试验阴性,支气管激发试验阳性哮喘患者的临床诊断价值。  

Objectives of Study:

This study investigated the correlation between fractional exhaled nitric oxide (FeNO), alveolar nitric oxide concentration (CaNO), and small airway function parameters in patients with bronchodilator-negative asthma. Additionally, it aimed to evaluate the clinical diagnostic value of combining FeNO, CaNO, and small airway function indices in asthma patients exhibiting bronchodilator-negative but bronchoprovocation-positive responses.

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:在经过患者同意后由参与临床研究的医师通过病例报告表进行采集。 数据管理:本研究中的所有数据均妥善保管,确保安全无丢失及泄露。不随意上传敏感信息及患者信息至公共平台。数据处理过程中,将患者的个人信息去敏感处理,并使用患者识别码替代患者姓名及ID。如需技术服务,确保数据相应加密处理,并签订保密协议

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

Data Collection: After obtaining patient consent, clinical investigators will collect data through case report forms (CRFs). Data Management: All research data will be securely stored to prevent loss or unauthorized disclosure. Sensitive information (including patient identifiers) will not be uploaded to public platforms. During processing, personally identifiable information (PII) will be de-identified and replaced with unique patient codes. If third-party technical services are required, data encryption and confidentiality agreements will be implemented.
