研究目的:

1. 主要研究目的 建立并验证一个基于胸部CT定量参数的哮喘诊断模型,旨在在存在呼吸道症状但尚未确诊的患者中,提升对哮喘可能性的早期识别能力。模型的开发将在单中心(上海市第一人民医院)队列基础上完成,并在独立外部验证队列(上海市第二人民医院)中评估其泛化能力和临床适用性。 2. 次要研究目的 (1)评估单一影像学指标(如LAA%、WA%、Pi10等)在哮喘预测中的独立诊断效能,通过ROC曲线与AUC值表征其识别能力; (2)比较不同影像参数组合构建的多因素Logistic回归模型的预测性能,包括灵敏度、特异度、AUC、校准度及决策曲线分析(DCA)表现; (3)探讨参数在不同临床亚群(如不同症状类型、性别、吸烟状态)中的预测表现差异。 3. 探索性研究目的 (1)分析结构参数与肺功能(如FEV?/FVC、FEF25–75%)、气道阻力(如R5-R20)、炎症标志物(如EOS、FeNO)之间的相关性,揭示结构-功能-炎症之间的耦合机制; (2)探索不同支气管级别(第3–8级)气道结构改变在哮喘患者中的分布特点及其与症状严重程度或功能受损的关联; (3)评估基于影像参数构建的模型在辅助临床决策(如是否推荐进一步激发试验,及与气道高反应性相关性)中的潜在价值。  

Objectives of Study:

1. Main Research Objective To establish and validate an asthma diagnostic model based on quantitative chest CT parameters, aiming to improve early identification of potential asthma in patients who have respiratory symptoms but have not yet been diagnosed. The model will be developed using a single-center cohort (Shanghai First People's Hospital) and its generalizability and clinical applicability will be assessed in an independent external validation cohort (Shanghai Second People's Hospital). 2. Secondary Research Objectives (1) To evaluate the independent diagnostic efficacy of individual imaging indicators (such as LAA%, WA%, Pi10, etc.) in predicting asthma, characterized by ROC curves and AUC values for their identification ability; (2) To compare the predictive performance of multivariate logistic regression models constructed from different combinations of imaging parameters, including sensitivity, specificity, AUC, calibration, and decision curve analysis (DCA); (3) To explore the differences in predictive performance of parameters across different clinical subgroups (e.g., different symptom types, gender, smoking status). 3. Exploratory Research Objectives (1) To analyze the correlation between structural parameters and lung function (such as FEV?/FVC, FEF25–75%), airway resistance (such as R5-R20), and inflammatory markers (such as EOS, FeNO), revealing the coupling mechanisms between structure, function, and inflammation; (2) To explore the distribution characteristics of airway structural changes at different bronchial levels (3rd–8th generation) in asthma patients and their association with symptom severity or functional impairment; (3) To assess the potential value of a model based on imaging parameters in supporting clinical decisions (e.g., whether to recommend further provocation tests and its association with airway hyperresponsiveness).
