FEF25–75 = forced inspiratory flow from 25% exhalation to 75% exhalation; FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; IC = inspiratory capacity; MVV = maximum voluntary ventilation; PEF = peak expiratory flow; RV = residual volume; TLC = total lung capacity; VC = vital capacity.
*Values of p < 0.05 are statistically significant.
