Relationship between change in total airway resistance (Raw) and change in lung clearance index (LCI) (n = 21). LCI and Raw were assessed by multiple breath nitrogen wash out and plethysmography (respectively) before and 6 months after bronchial thermoplasty. After bronchial thermoplasty, the percentage fall in resistance was positively correlated with reduced LCI
