5.Conclusion:
Overall, our results suggested that R5, X5, AX, Fres may be able to
predict acute attack or loss of control of asthma, while R20, R5-20
could not. Besides, our research further demonstrated that peripheral
airway injury had a good correlation with asthma exacerbations. It may
show that in clinical work, the role of peripheral airway injury should
be recognized, and timely identification and intervention should be made
to reduce the frequency of acute asthma attacks.
