WebIn an analysis of flow–volume curves from 5,140 participants (50% pediatric) selected from three communities , Kapp and colleagues defined the β-angle by joining the residual volume point of the MEFVC to the flow point at mid-volume, and then joining the flow point at mid-volume to peak flow. A β-angle less than 180° indicates a concave curve.
