  4. aA diagnosis of postinfective bronchiectasis was made if the patient reported a history of symptoms due to bronchiectasis with an onset after a severe respiratory infection, such as pneumonia or tuberculosis, according to clinical judgment and regardless of the latency between the event and the occurrence of symptoms of bronchiectasis [38]
  5. bBronchiectasis associated with COPD was diagnosed in the presence of a smoking history of at least 10 pack-years with airflow obstruction (FEV1/FVC ratio < 0.7) according to the Global Initiative for Chronic Obstructive Lung Disease [20]
