GATA3 and asthma: However, when performing the correlation test using the subgroups of asthmatics EOS high and EOS low, only five of the subsets in the EOS high group showed significant correlation to FeNO or FEV1 reversibility and none in the EOS low group (Table 3), which implies that GATA-3 and RORγt expression may have clinical relevance in asthma subgroups.
