  1. Bolding indicates statistical significance. The value of B represents the unstandardized regression coefficient; The value of β represents the standardized regression coefficient. SE standard error; 95% CI: 95% confidence interval for B; FVC Forced vital capacity; FEV1 Forced expiratory volume in one second; FEV1/FVC The ratio of forced expiratory volume in one second to forced vital capacity; FEF25: Forced expiratory flow 25% of FVC; FEF50 Forced expiratory flow 50% of FVC; MMEF Maximal mid− expiratory flow; % pred: % predicted.
