Longitudinal measurements of exhaled nitric oxide in children-what is a significant change in FENO?

Background The principle aim of this study was to describe the variability of exhaled nitric oxide (FENO) concentrations over 10 months in children with and without asthma. Methods FENO was measured on six occasions at 2‐month intervals in a community‐based cohort of children with and without asthma...

Summary:Background The principle aim of this study was to describe the variability of exhaled nitric oxide (FENO) concentrations over 10 months in children with and without asthma. Methods FENO was measured on six occasions at 2‐month intervals in a community‐based cohort of children with and without asthma. Results There were 178 children recruited, 47 had asthma, mean age 9.6 yr. A total of 851 FENO measurements were made. The change in FENO values was positively associated with the initial FENO concentration (p
