a
From Student's paired t-test.
EILO, exercise induced laryngeal obstruction; IMT, inspiratory muscle training; FVC, forced vital capacity; FEV1, forced expiratory volume in first second time; FEF50, forced expiratory flow at 50%; FIF50, forced inspiratory flow at 50%; SD, standard deviation.
*
One patient with supraglottic score 1 and glottic score 1 was included because of large involvement from a retroflex epiglottis (not assessed in the scoring system).
