Fig 1 A, Forced expiratory flow at functional residual capacity (V′max,FRC) in multiple-trigger wheezers was significantly lower than that seen in nonwheezers. B, Increased airway responsiveness (ie, the provocative dose of methacholine causing a 40% decrease in V′max,FRC [PD40 V’max,FRC]) of 0.90 mg or less was significantly more common in multiple-trigger wheezers than in nonwheezers.
