- Brief Summary
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.
