Fig. 6From: Plasma, urine and ligament tissue metabolite profiling reveals potential biomarkers of ankylosing spondylitis using NMR-based metabolic profilesAltered metabolic pathways for the most relevant distinguishing metabolites (potential biomarkers) between the patients with AS and the healthy control subjects and patients with femoral neck fracture. Green boxes indicate metabolites that were up-regulated in AS, while red boxes indicate metabolites that were down-regulated.
