Inclusion criteria

We included patients with asthma based on the following criteria:
1. Postbronchodilator FEV1/FVC <0.7 or lower limit of normal;
2.Documented history of asthma. Patients diagnosed for the first time required follow-up medical records  to confirm the diagnosis of asthma;
3. The criteria outlined in Global Initiative for Asthma (GINA) are as follow: (1). repeated attacks of wheezing, shortness of breath, chest tightness, cough, and relevance to allergens, cold air, physical and chemical stimulation, infection of the upper respiratory tract, exercise, etc.; (2). when an attack occurs, scattered or diffuse wheezing of the expiratory phase can be heard with a prolonged expiratory phase; (3). these symptoms can be relieved by treatment or resolve spontaneously; (4) objective evidences of variable airflow limitation:  1).positive bronchial provocation test or exercise test; 2) positive bronchodilation test; 3) variation of daily peak expiratory flow (PEF)>10%, or variation of weekly PEF>20%. 
The patients, according to I-Ⅲ, and meeting at least one of Ⅳ items, excluding other conditions causing wheezing, shortness, chest tightness, or cough, can be diagnosed with asthma. 
The inclusion criteria for patients with COPD were as follows: 
1.Documented history of COPD. Patients diagnosed for the first time required follow-up medical records to confirm the diagnosis of COPD;
2.Participants were defined as having COPD according to Global Initiative for Chronic Obstructive Lung Disease(GOLD) guidelines, with a history of smoking, exposure to occupational dust and chemical substances, perennial cough, expectoration, dyspnea, and a post-bronchodilator FEV1/FVC <70%,excluding other conditions causing airflow limitation.
Selection of validation samples
Inclusion and exclusion criteria for validation samples are the same as those for the training samples, which are applied to internal and external validations.

排除标准：

支气管哮喘患者的排除标准：①排除支气管扩张、肺结核纤维化病变、严重的间质性肺疾病、弥漫性泛细支气管炎、闭塞性细支气管炎。②通过胸部CT排除大气道阻塞的患者。慢性阻塞性肺疾病患者的排除标准：①排除支气管扩张、肺结核纤维化病变、严重的间质性肺疾病、弥漫性泛细支气管炎、闭塞性细支气管炎。②中心气道塌陷的患者也需要通过胸部CT检查排除。两类患者均需排除支气管哮喘-慢阻肺重叠综合征（Asthma-Chronic Obstructive Pulmonary Disease Overlap Syndrome，ACOS）存在的可能，ACOS病人必须具备主要标准和一个次要标准。三个主要标准是：（1）持续性气流受限（吸入支气管舒张剂后FEV1/FVC＜70%或者小于正常值下限）、年龄超过40岁。（2）至少吸烟10包.年或者等效的生物燃料。（3）40岁以前有可记录的哮喘历史，或者吸入支气管舒张剂后FEV1改善超过400ml。次要标准包括：（1）有特异反应性鼻炎或者过敏性鼻炎。（2）在2次或者多次随访时吸入支气管舒张剂后FEV1改善率超过12%且大于200ml。（3）外周血嗜酸性粒细胞超过200/ml。

Exclusion criteria：

Exclusion criteria for patients with bronchial asthma: 1. the presence of bronchiectasis, fibrotic lesions caused by pulmonary tuberculosis, interstitial lung disease, diffuse bronchiolitis, or bronchiolitis obliterans; 2. large airway obstructions using chest computed tomography (CT). The exclusion criteria for patients with COPD were as follows: 1. the presence of bronchiectasis, fibrotic lesions caused by pulmonary tuberculosis, interstitial lung disease, diffuse bronchiolitis, or bronchiolitis obliterans,; 2.evidence of collapsed central airways using chest computed tomography (CT). Patients with asthma–chronic obstructive pulmonary disease overlap syndrome (ACOS) were excluded from the study. Such patients must meet all major criteria and at least one minor criterion. The three major criteria include: 1.persistent airflow limitation (FEV1/FVC <70% or less than the lower limit of normal post-bronchodilator inhalation) and age >40 years; 2. a smoking index of at least 10 pack.years or equivalent exposure to biofuels; 3. a documented history of asthma with onset before age 40 or an increase in FEV1 of >400 mL post-bronchodilator. The minor criteria include :1.a documented history of atopic or allergic rhinitis; 2. an increase in FEV1 by >12% and >200 mL post-bronchodilator inhalation on at least two separate visits; 3.peripheral blood eosinophil counts >200 cells/µL.
