No significant association was found between Eo/B CFUs and the occurrence of wheezing symptoms ever (IL-3: p = 0.926; IL-5: p = 0.379; GM-CSF: p = 0.943), recurrent wheezing (IL-3: p = 0.574; IL-5: p = 0.415; GM-CSF: p = 0.909), bronchitis (IL-3: p = 0.281; IL-5: p = 0.067; GM-CSF: p = 0.095), or obstructive bronchitis (IL-3: p = 0.308; IL-5: p = 0.495; GM-CSF: p = 0.663). This evidence concerns the gene CSF2 and bronchitis.
