Primary outcomePrimary: Exhaled Nitric Oxide at Baseline and Over the Observational Period — 15.1; 9.9; 13.7; 8.6 parts per billion
Summary
Hypotheses: 1) Airway pH regulation is abnormal in severe asthma; 2) In severe asthma, there is formation of cytotoxic nitrogen oxides and loss of beneficial nitrogen oxides in the airways
