Most studies investigating predictors of exacerbations were performed in COPD patients participating in pharmacological clinical trials who usually have moderate to severe airflow obstruction. This study was aimed to investigate whether predictors of COPD exacerbations depend on the COPD population studied.enArchived with thanks to International journal of chronic obstructive pulmonary diseasePrediction models for exacerbations in different COPD patient populations: comparing results of five large data sources.ArticleInt J Chron Obstruct Pulmon Dis 2017; 12:3183-94
