{"cited_by_count":2665864,"description":"This cluster of papers focuses on the standardisation, diagnosis, and management of Chronic Obstructive Pulmonary Disease (COPD), including the use of spirometry for lung function testing, global burden analysis, exacerbation frequency, and the development of guidelines for treatment and prevention. It also explores the relationship between COPD and systemic inflammation, comorbidities, and mortality.","display_name":"Chronic Obstructive Pulmonary Disease (COPD) Research","domain_id":"4","external_ids":{"openalex":"https://openalex.org/T10143","wikipedia":"https://en.wikipedia.org/wiki/Chronic_obstructive_pulmonary_disease"},"field_id":"27","id":"T10143","keywords":[{"display_name":"chronic obstructive pulmonary disease","id":"chronic-obstructive-pulmonary-disease","score":0.5511,"url":"https://openalex.org/keywords/chronic-obstructive-pulmonary-disease"},{"display_name":"COPD exacerbations","id":"acute-exacerbation-of-copd","score":0.7365,"url":"https://openalex.org/keywords/acute-exacerbation-of-copd"},{"display_name":"lung function","id":"lung-function","score":0.2089,"url":"https://openalex.org/keywords/lung-function"},{"display_name":"emphysema","id":"emphysema","score":0.4852,"url":"https://openalex.org/keywords/emphysema"},{"display_name":"pulmonary rehabilitation","id":"pulmonary-rehabilitation","score":0.5464,"url":"https://openalex.org/keywords/pulmonary-rehabilitation"},{"display_name":"FEV1","id":"fev1","score":0.3387,"url":"https://openalex.org/keywords/fev1"},{"display_name":"spirometry","id":"spirometry","score":0.4108,"url":"https://openalex.org/keywords/spirometry"},{"display_name":"pulmonary function tests","id":"pulmonary-function-tests","score":0.3967,"url":"https://openalex.org/keywords/pulmonary-function-tests"},{"display_name":"chronic bronchitis","id":"chronic-bronchitis","score":0.414,"url":"https://openalex.org/keywords/chronic-bronchitis"},{"display_name":"FEV1/FVC ratio","id":"fev1-fvc-ratio","score":0.4772,"url":"https://openalex.org/keywords/fev1-fvc-ratio"},{"display_name":"airflow obstruction","id":"airflow-obstruction","score":0.5683,"url":"https://openalex.org/keywords/airflow-obstruction"},{"display_name":"acute exacerbation","id":"acute-exacerbation","score":0.3974,"url":"https://openalex.org/keywords/acute-exacerbation"},{"display_name":"long-acting beta2-agonists","id":"long-acting-beta-agonists","score":0.3824,"url":"https://openalex.org/keywords/long-acting-beta-agonists"},{"display_name":"lung function decline","id":"lung-function-decline","score":0.2945,"url":"https://openalex.org/keywords/lung-function-decline"},{"display_name":"St George's Respiratory Questionnaire","id":"st-george-s-respiratory-questionnaire","score":0.6744,"url":"https://openalex.org/keywords/st-george-s-respiratory-questionnaire"},{"display_name":"COPD Assessment Test","id":"copd-assessment-test","score":0.8666,"url":"https://openalex.org/keywords/copd-assessment-test"},{"display_name":"long-acting muscarinic antagonist","id":"long-acting-muscarinic-antagonist","score":0.7255,"url":"https://openalex.org/keywords/long-acting-muscarinic-antagonist"},{"display_name":"tiotropium","id":"tiotropium","score":0.6626,"url":"https://openalex.org/keywords/tiotropium"},{"display_name":"alpha-1 antitrypsin deficiency","id":"alpha-1-antitrypsin-deficiency","score":0.3081,"url":"https://openalex.org/keywords/alpha-1-antitrypsin-deficiency"},{"display_name":"6-minute walk distance","id":"6-minute-walk-distance","score":0.2397,"url":"https://openalex.org/keywords/6-minute-walk-distance"},{"display_name":"chronic respiratory disease","id":"chronic-respiratory-disease","score":0.2057,"url":"https://openalex.org/keywords/chronic-respiratory-disease"},{"display_name":"diffusing capacity for carbon monoxide","id":"diffusing-capacity-for-carbon-monoxide","score":0.2084,"url":"https://openalex.org/keywords/diffusing-capacity-for-carbon-monoxide"},{"display_name":"COPD management","id":"copd-management","score":0.8982,"url":"https://openalex.org/keywords/copd-management"},{"display_name":"COPD severity","id":"copd-severity","score":0.812,"url":"https://openalex.org/keywords/copd-severity"},{"display_name":"COPD treatment","id":"copd-treatment","score":0.8901,"url":"https://openalex.org/keywords/copd-treatment"}],"legacy_keywords":["COPD","spirometry","lung function","pulmonary disease","global burden","respiratory","obstruction","exacerbations","management","diagnosis"],"openalex_id":"https://openalex.org/T10143","source_created_date":"2024-01-23T15:27:05","source_updated_date":"2026-10-17T03:02:00","subfield_id":"2740","url":"/topics/T10143","works_api_url":"https://api.openalex.org/works?filter=topics.id:T10143","works_count":218213,"label":"Chronic Obstructive Pulmonary Disease (COPD) Research","provider":"openalex","revision":"b7e4d8dad40e1299","taxonomy_revision":"f050b5d4780b1289","title":"Chronic Obstructive Pulmonary Disease (COPD) Research","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36108824076004778","address_version":"morton4x16-v1","coordinates":[4,27,2740,10143],"answer_status":"Directory metadata;
