Adolescents’ characteristics
A total of 44 adolescents were screened; two terminated their participation in the study, and one experienced exacerbated symptoms before the 2nd visit (Figure 1). Most of the adolescents were male and had a normal weight, controlled asthma (ACT≥20), early-onset asthma, and atopic conditions (Table 1). The adolescents in the FAO group reported more previous asthma hospitalizations, more cases of early-onset asthma, and more cases of atopic conditions. Besides, they presented poorer lung function (FEV1 and FEV1/FVC ratio), and a poorer BD response than did the non-FAO group (p<0.05, Table 1). On the other hand, no significant differences were observed between FAO and non-FAO groups in terms of sex, BMI, inhaled corticosteroid dose, ACT score, blood eosinophils, and FVC % of the predicted value (p>0.05, Table 1).
