: The research aimed to validate new graphic parameters for measuring the concavity of the Expiratory Flow-Volume Curve (EFVC) . This is a critical diagnostic tool used to assess lung function and airway obstruction. Methodology :
: The study analyzed 61 COPD patients drawn from the Seoul National University Airway Registry (SNUAR) and the Korean Obstructive Lung Disease (KOLD) cohort.
: Researchers utilized Graphical Analysis 3.4 (Vernier Software) to integrate the area under the curve and calculate new parameters like the Rectangular Area Ratio (RAR) . Key Findings :
Based on published findings associated with this identifier,

The study found that patients with more "left-shifted" or "shorter time to peak" patterns typically correlated with more severe stages of COPD (GOLD stages II-III). :
: The primary limitations cited by the authors included a small sample size and the fact that most subjects already had moderate-to-severe COPD, leaving the efficacy for "mild" cases less clear. Technical File Note
