Bronchial hyperresponsiveness in an adult population in Helsinki – decreased FEV1 the main determinant

The Clinical Respiratory Journal, 04/25/2012

Of the adult population of Helsinki, 21% showed bronchial hyperresponsiveness to inhaled histamine (BHR). The main determinants were decreased FEV1 and airway obstruction.
