Expiratory relative flow-time values on each day of testing (reproducibility). Results are shown as mean (cross), median (horizontal line), quartiles (box) and 10-90th percentile (whiskers). Results from each day of testing represent the mean of three breaths analysed for each horse. P values were determined by one-way RM-ANOVA. Expiratory zero to peak (ezp) values represent the relative percentage of peak inspiratory flow measured at 25, 50 and 75% of the time from zero to peak flow; expiratory peak to zero (epz) values represent the relative percentage of peak inspiratory flow measured at 25, 50 and 75% of the time from peak to zero flow
