Conclusion
We identified tree pollen allergy, nocturnal cough, wheezing, a
FEF75 < 65% and a younger age as significant
predictors of AHR. Combining these predictors in a weighted multivariate
score improved the diagnostic value. This novel score might be used in
children suspected of having asthma, but without an obstructive pattern,
to identify those who probably will show a positive response to the MCC
as well as to substantiate the result of the MCC. Further prospective
studies may help to demonstrate the predictive value of this score.
