Timing of laryngeal obstruction in exercise-induced laryngeal obstruction

Inspiratory laryngeal obstruction across rest, incremental ramp exercise to a symptom-limited peak and recovery. Laryngeal obstruction in the entire group is quantitated at the level of the (A) glottis and (B) supraglottis, respectively. Laryngeal obstruction in subjects with moderate or severe inspiratory glottic adduction in any test window is also quantitated at the level of the (C) glottis and (D) supraglottis, respectively. Confidence intervals surround estimates and are based on the scoring scale of ROKSUND et al^[1].
