Definition of Abbreviations: SB-eNO = single-breath exhaled nitric oxide; ICS = inhaled corticosteroids; FH = family history. N=32 subjects. ß Coefficient represents change in lung function z-score associated with each variable or increment of a variable (e.g 10ppb increment of SB-eNO). Bold type denotes a statistically significant association.
