From: Airways Disease: Phenotyping Heterogeneity Using Measures of Airway Inflammation
Airway diseases are composed of a number of domains that can be assessed by several outcome measures. The combination of outcome measures allows for phenotyping the heterogeneity, which impacts on clinical management and research. AHR = airway hyperresponsiveness; BD = bronchodilator; BMI = body mass index; CRP = C-reactive protein; HRCT = high-resolution computed tomography, PEFR = peak flow reading; PFTs = pulmonary function tests.
