A box plot of FeNO values (ppb) at Visit 1 and Visit 2 for the ITT population with overlaid line plotting of all subjects in the ITT population. The lower and upper bounds of the boxes represent the 25th and 75th percentiles of the distributions (the interquartile range) and the internal box symbols and horizontal lines within each box represent the mean and median values, respectively. The figure indicates the diminution of FeNO values across the population as a result of corticosteroid therapy
