DOI: 10.1186/s12931-020-01450-9
Abstract: Background Currently, the diagnosis of chronic obstructive pulmonary disease (COPD) is not uniform, COPD guidelines recommend fixed ratio (FR), whereas ATS and ERS define airflow obstruction based on lower limit of normal (LLN). We aim… read more here.

DOI: 10.4187/respcare.07536
Abstract: BACKGROUND: Although specific guidelines exist for diagnosing COPD on the basis of spirometry testing data (FEV1/FVC < 0.70 or above the lower limit of normal), the literature suggests that overdiagnosis is common. Whether overdiagnosis increases… read more here.
