This is the protocol for a review and there is no abstract. The objectives are as follows: To evaluate the efficacy of tailoring asthma interventions based on exhaled nitric oxide (FeNO) in comparison to not using FeNO i.e. management based on clinical symptoms (with or without spirometry/peak flow) and/or asthma guidelines for asthma related outcomes in adults.
