Results
Oscillometric parameters, including R5, R5-R20, X5, Fres, and AX, but not FEV1, significantly worsened after a 3-month period of observation in the high FeNO group but not in the low FeNO group. FeNO decreased significantly in the high FeNO group but not in the low FeNO group. There were correlations between baseline FeNO levels and changes in R5 and R5-R20 in the high FeNO group. Multiple logistic regression analysis revealed that R5 and R5-R20 were associated with higher FeNO levels.

Baseline Characteristics
Of the 97 subjects who completed the study, 28 (28.9%) patients had FeNO levels > 35 ppb. There was no difference in the demographic, ACT, and lung function data between high and low FeNO groups at baseline except for FeNO levels
Participant flow
One hundred and forty-three patients were screened and 46 patients were excluded upon entry because of asthma exacerbation, a change in medications, or difficulty in taking measurements.
Adverse events
none
Outcome measures
The patients were classified into high or low FeNO groups (FeNO > 35 ppb or < 35 ppb) based on the baseline FeNO levels. The primary outcomes were the changes in oscillometric parameters.
