Association between fractional excretion of nitric oxide (FeNO, x-axis) with the acute asthma intensity research score (AAIRS, upper panel) and with %-predicted forced expiratory volume in 1-second (% predicted FEV1, lower panel). The plots depict a smooth adjusted association derived from multivariable regression models that included the covariates, age, sex, BMI, asthma severity score, albuterol and inhaled and oral corticosteroid use.
