Figure 6. (A) Endoscopic polyp score reduction is well correlated with the Eos/SPT ratio (P=0.005). Higher baseline eosinophil count along with low number of allergen SPT positives predicts better response to benralizumab. (B) Similarly, the Eos/SPT ratio correlated with CT scan polyp score and also reached statistical significance (P=0.048). Four-parameter logistic curves interpolate the correlation inflection points.
