Patients who had a FeNO level greater than 50 ppb were more than twice as likely to improve on steroids treatment than patients who had lower levels of FeNO (P=0.046), said Victoria Carter, research operations director for the Singapore-based Observation and Pragmatic Research Institute.
For every 10 ppb increase in FeNO, the researchers calculated an odds ratio of 1.17 that steroids would bring improvement.
