Association between hydrogen levels, glycan metabolism and GI symptom severity. a Network of associations between CAZy family and hydrogenase group. An edge represents absolute Spearman’s correlation coefficients above 0.4. All kept associations were positive. The node shape indicates CAZy family (circle) and hydrogenase (triangle). The color code indicates the known glycan substrates of the CAZy family. b Linear discriminant analysis (LDA) scores for prediction of IBS severe vs control as a function of gut metagenomic hydrogenase [FeFe] group. c Relative abundance of gut metagenome hydrogenase [FeFe] A3 as a function of health status
