Reply: An index of maximal expiratory flow–volume curve with different features related to central and peripheral concavity

Key Points

• To address the relationship between features of the MEFV curve's concavity and the incidence of COPD and respiratory symptoms.
• Responded to previous research inquiries regarding the MEFV curve
• Referred to findings from the Tasmanian Longitudinal Health Study (TAHS) about concavity properties
• Highlighted correlations with respiratory symptoms and COPD incidence
• Concavity of the MEFV curve is noted to be associated with COPD incidence
• Variations in central and peripheral concavity are discussed in context of respiratory health
