  		Fig. 7A. —Graphs display results of pulmonary function tests (percentage of predicted values) in the three patterns. Graphs show mean values and standard deviations for total lung capacity (TLC) (A), forced expiratory volume in 1 sec on vital capacity (FEV1/VC) (B), and diffusing lung capacity for carbon monoxide (TCO) (C).
