Evidence Reports Now Available

The Clinical Utility of Fractional Exhaled Nitric Oxide (FeNO) in Asthma Management
(Systematic Review, released 12/20/2017)

Selected Key Findings:

  • Depending on the FeNO cutoff, the likelihood of having asthma in people ages 5 years and older increases by 2.8 to 7.0 times given a positive FeNO test result.
  • FeNO is modestly more accurate in diagnosing steroid-naïve asthmatics, children (ages 5-18), and nonsmokers than other patients suspected to have asthma.
  • FeNO results can predict which patients will respond to inhaled corticosteroid therapy.
  • Using FeNO to manage long-term control medications including dose titration, weaning, and monitoring of adherence, reduces the frequency of exacerbations.
  • There is insufficient evidence supporting the use of FeNO in children (ages 0-4) for predicting a future diagnosis of asthma.

Methods for Evaluating Natural Experiments in Obesity: A Systematic Evidence Review
(Systematic Review, released 12/1/2017)

Selected Key Findings:

  • Relevant programs, policies, or built environment changes were evaluated in 156 natural experiments, 118 experimental studies, and 20 other studies.
  • Criteria for a data system (source exists, is available for research, is sharable, and has outcomes of interest) were met by 106 data sources.
  • Thirty-seven percent of U.S. data systems were linked to secondary data.
    Outcome measures included dietary behavior (148 studies), physical activity (152 studies), childhood weight (112 studies), and adult weight (32 studies).
  • Natural experiments most commonly used regression models comparing exposed and unexposed groups at one time.
  • Natural experiments generally had moderate risk of selection bias and high risk of bias for losses to follow-up.
  • Research could be advanced by more use of data dictionaries, reporting standards on data linkage, long-term obesity-related outcomes, and study designs with multiple pre- and postexposure time points.
