Panel A: enrollment single-breath exhaled nitric oxide (SB-FENO) concentrations were significantly higher among subjects who experienced persistence of wheezing (closed triangles) at age 3 years than among those subjects who experience resolution (open circles) of wheezing (35.1 ppb vs. 18.6 ppb, p < .001). Analysis conducted using an unpaired t test. Panel B: enrollment tidal-FENO concentrations were not significantly different between subjects with persistence of wheezing (closed triangles) and among those whose wheezing resolved (open circles) (8.4 ppb vs. 7.1 ppb, p = 0.4). Analysis conducted using the Mann-Whitney test.
