From: Distinctive lung function trajectories from age 10 to 26 years in men and women and associated early life risk factors – a birth cohort study

Fig. 2

Lung function trajectories of Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), the ratio of the FEV1/FVC, and Forced Expiratory Flow 25–75% (FEF25–75) developments from age 10 to age 26 in female and male participants. Legend: The best fit for FVC and FEV1 trajectories in female and male participants were two quadratic patterns. For FEV1/FVC trajectories one linear and one quadratic trajectory gave the best fit, whereas for the three FEF25–75 trajectories in female and male participants modeling was most appropriate with three quadratic trajectories each
