Figure 1: FeNO levels in different age categories. FeNO had a significant decreasing trend with increasing age. The average FeNO level in different age group were 64.6 ppb, 49.1 ppb, 36.2 ppb, 43.8 ppb and 37.3 ppb, respectively. There were 6, 4, and 3 outliers in age group 38-47, 48-57, and ≥58, respectively. FeNO, fractional exhaled nitric oxide.
