Correlation between respiratory function test (FEV1) and respiratory impedance test. A Correlation between respiratory function test (FEV1) and respiratory impedance are shown. n = 50 in each panel. *p < 0.05,**p < 0.01 by the Pearson correlation coefficient. B The improvement rates (%) of FEV1 and R5 after three months of dupilumab treatment in patients with FEV1/FVC above and below the mean (80.8%) are shown. n = 50 in each panel. *p < 0.05, **p < 0.01 by unpaired t test
