Subjects
Among 72 patient records (mean age 4,98 ± 0,94 yrs; 64% boys) preliminarily identified as meeting the previously mentioned anamnestic inclusion criteria, 36 (mean age 5,15 ± 0,99 yrs; 64% boys) were associated with high-quality pulmonary function measurements for both IOS and spirometry and therefore selected for the subsequent statistical analysis. Their clinical characteristics are summarized in Table 1.
The selected patients were 23 male and 13 female with a mean age of 5,15 ± 0,99 years; 19 of 36 were atopic and 14 took control medications, specifically 1 LTRA (Montelukast), 5 ICS (Fluticasone) and 8 ICS + LABA (Fluticasone + Salmeterol).
