Increased biomarkers cause changes in the adjusted odds ratio for asthma. A Adjusted odds ratios (adjusted by age and Sex) of having asthma based on progressively increasing FeNO. B Adjusted odds ratios of having asthma based on progressively increasing B-Eos counts. Notes: Logistic regression models were used. P values were calculated by the Wald test. Estimates were adjusted. The Cochran–Armitage trend test was used to test whether there is a certain trend between two categorical variables. OR, odds ratio; CI, confidence interval
