Baseline lung function measurements
The baseline lung function measurements are presented in Table 2 and were characterized by a good correlation between FEV1 and the main IOS parameters. Specifically, the Spearman’s rank correlation coefficient (ρ) between FEV1 and R5, X5 and AX was of -0,67 (p<0.0001), 0,62 (p<0.0001) and 0,6 (p=0.0001), respectively.
