DOI: 10.1136/bmjgast-2022-000870
Abstract: Background Alanine aminotransferase (ALT) is a marker of hepatic damage and its range can be affected by viral hepatitis, alcoholic hepatitis and non-alcoholic fatty liver diseases. We aimed to study the factors associated with higher… read more here.

Abstract: Background and Objectives: Creatine kinase (CK) is a commonly used screening test for neuromuscular disorders (NMDs). However, hyperCKemia can result from several pathologic and physiologic causes. We analyzed neuromuscular disorders in noninfant children with hyperCKemia… read more here.

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.

Fixed Ratio Versus Lower Limit of Normal: Health Status and Risk Factors for COPD Overdiagnosis
Sign Up to like & getrecommendations! Published in 2019 at "Respiratory Care"
DOI: 10.4187/respcare.07069
Abstract: BACKGROUND: The threshold of the lower limit of the normal range of lung function has been suggested to be more accurate than the 0.7 fixed ratio (FEV1/FVC < 0.7) for a diagnosis of COPD. We… 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.
