Table 4 Levels of fractional exhaled nitric oxide (FeNO) in children hospitalized for bronchiolitis and in an age matched control group, by asthma and atopic status

From: Exhaled nitric oxide is related to atopy, but not asthma in adolescents with bronchiolitis in infancy

   Post-bronchiolitis group (n = 105) Control group (n = 89)
  N FeNO 95% CI P-values*vs. healthy N FeNO 95% CI P-values* vs. healthy
Healthy 62 8.1 6.8, 9.6 Reference 50 7.6 6.4, 9.1 Reference
Atopic non-asthmatic 20 13.6 10.1, 18.4 0.010 29 19.5 15.6, 24.5 <0.001
Current non-atopic asthma 14 7.2 5.0, 10.4 0.920 5 9.7 5.6, 16.8 0.781
Current atopic asthma 9 12.3 7.8, 19.2 0.237 5 21.4 12.4, 36.9 0.002
