FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity. ^ Data are nonparametric, presented as median [quartile 1, quartile 3], within-group changes analyzed by Wilcoxon matched pairs signed-rank test and group comparison performed using Wilcoxon rank-sum test. # Data are normally distributed and presented as means ± SEMs, within group changes analyzed by paired t-test and group comparison performed using two-sample t-test. § p < 0.05 versus control group at baseline. † Difference in change from 0 to 4 h within group. * Difference in change from 0 to 4 h between the soluble fibre and control group.
