Mixed-Model Treatment Means of Pulmonary Function and Exhaled Nitric Oxide

The data markers indicate geometric means and the error bars indicate 97.5% confidence intervals. FEV1 indicates forced expiratory volume in the first second of expiration. No significant differences in prebronchodilator FEV1, postbronchodilator FEV1, or albuterol-induced reversibility were observed. The BBA group had very little change in exhaled nitric oxide over the course of the trial because dosing of inhaled corticosteroids was adjusted to control exhaled nitric oxide. The SBA group showed a small and statistically significant increase in exhaled nitric oxide over the course of the trial vs the BBA group (P=.007). Level of exhaled nitric oxide in the SBA group did not differ significantly from the PABA group (P=.15).
