Referent category. Numbers represent mean difference (with 95% CIs) generated using linear mixed models adjusted for age, having a cold or flu, height, number of cigarettes smoked and use of respiratory medication. A random intercept for participant was included in the models.
FEV1, forced expiratory volume in the 1 s; PEF, peak expiratory flow.
