From: Raised-Volume Forced Expiratory Flow-Volume Curve in Healthy Taiwanese Infants
Comparison of various reference curves. Present regressions of forced vital capacity (FVC) (A), forced expiratory volume at 0.5 (FEV0.5) (B), and forced midexpiratory flow (FEV25–75) (C) in the study compared with previously published reference data.
